Introduction : In the previous chapters we have presented a few of the Asanas and other preparatory practices. Now we move on to Bandhas and Mudras. They are neuro-muscular locks and gestures. Bandhas are safety locks used during the process of breath-holding-Kumbhakas. These Bandhas and Mudras are ad­vanced techniques in Hathayoga used mainly for culturing of emotions.

Types of Bandhas:

Jalandhara Bandha (The Chin Lock)

Explanation : Jalandhara Yogi discovered this Bandha. Hence Jalandhara Bandha was named after him. There is the Jalandhar city in Punjab. The word "JALA" refers to the brain and the nerves passing through the neck and "DHARA" denotes the upward pull.
Description: (a) Sit in a comfortable position like Vajrasana, Padmasana in any meditative posture.

  • Keep the back erect.
  • Place the palms on the top of the knees.
  • Relax the whole body and close the eyes.
  • Inhale deeply, retain the breath inside, bend the head forward and press the
    chin tightly against the sternum.
  • The chin is to be tightly set in the Jugular notch.
  • Stay in the final pose for as long a time you can comfortably able to retain
    the breath.

(h)  This is Jalandhara Bandha.

Benefits : The chin lock closes the wind pipe and compresses various organs including the sinus receptors which are located in the throat region. The receptors are pressure sensitive and so the compression they receive during the Jalandhara Bandha slows down the heart
The bandha cleans the nasal passages and regulates the flow of blood and prana to the heart, head and the endocrine glands in the neck. The thyroid and parathyroid glands are massaged and their functioning improved. If Pranayama is performed without Jalandhara Bandha pressure is immediately felt in the heart, brain, eye balls and in the inner ear. This may lead to dizziness.
Jalandhara accelerate venous drainage from the cephalic region i.e. vital
organs in head and neck. The improved venous drainage will check the
accumulation of CO2in and around the respiratory centres and thereby enable
a person to hold the breath for a longer time.
Concentration : Concentration on Vishuddhi Chakra
Caution: Persons with neck pain, high blood pressure or heart ailments should
not practice without expert guidance.

2. Mula Bandha (Perineum contraction lock)

Explanation : Mula means root or origin or corner. It refers to the principal
region between the anus and the genitals.
Description: (a) Mula bandha should be attempted first in the internal retention
after inhalation.
(b)   The practice of contracting the anal sphincter muscles (asvim mudra) helps
one to master mula bandha.
(c)   Asva means a horse. This mudra is so called because it suggests the staling
of ahorse.(d) It should also be learnt while doing various asans like pavana muktasana, ustrasana, paschimottanasana and vipareetakami mudra. Concentration : Concentration on Muladhara Chakra. Sequence : Jalandhra, Mula and Uddiyana Bandhas in Pranayama practice. Benefits : The pelvic nerves are stimulated and the associated sexual and eliminative organs toned. The sphincter muscles of the anus are strengthened and intestinal peristalsis is stimulated. In this way constipation and piles can be removed. This generates vitality and helps to awaken the Kundalini. Caution : It should be practised step by step with proper care and perfect guidance. If any mistake occurs in mulabhanda dry stools are passed.

3. Uddiyana Bandha (Navel Lock)

Explanation : Uddiyana, which means flying up, is an abdominal grip. Ud­diyana is different from the uddiyana bandha Description : (a) Sit in meditative pose.

  • Close the eyes and relax the whole body.
  • The abdominal viscera, particularly above and below the navel are to be
    pulled back with lock.
  • This is practised at the end of Kumbhaka before the beginning of Rechaka.
  • The practice is optional during Pranayama.

Uddiyana Bandha (Navel Lock)

Concentration: On Manipura chakra. Sequence : Jalandhara Bandha, Mula Bandha and Uddiyana Bandha. Benefits: Manipura chakra, located in the region of the navel is stimulated. It purifies the navel through which the wind is purified.
These three Bandhas Jalandhara, Mula and Uddiyana form one group called Bandha Traya (the lock trinity). These Bandhas are used exclusively as locks during Kumbhaka i.e. to restrain and close the passage for the breath. Jalandhara Bandha is used during Antara-Kumbhaka and Uddiyana Bandha in Baashya Kumbhaka. Mula Bandha can be done during Purakas, Kumbhaka, Rechaka and also in Japa and meditation. These Bandhas prevent the building up of tension in the head.

Types of Mudras

Mudras in general are used mainly in three fields.

  1. Rituals in performing certain worships.
  2. Dance (to express the emotions and feelings through bodily gestures) and
  3. Hathayoga (to help in stabilizing the mind)

We will limit ourselves to the region of Hatha yoga which includes Asanas, Pranayamas, Bandhas, Mudras and Shat kriyas. Many of the Sanskrit yoga texts take Bandhas and Mudras as a single unit.
According to Gheranda samhita, there are mainly 25 Mudras, where as Hatha pradipika and Hatharatnavali describes only 10 of these. Among them the following eleven are the most important ones :-
(1) Mahaa mudra, (2) Mahaa Bandha, (3) Mahaa vedha (4) Viparitakarani, (5) Vajroli, (6) Sakticalani (7) Uddiyana Bandha (8) Jalandhara Bandha (9) Mula Bandha (10) Yoni Mudra (11) Khecari - Mudra.

Now we will briefly describe few common mudras.
1. Yoni or Shanmukhi Mudra (six faced Psychic Gesture)

Explanation : This is a technique of Nada yoga " Sravanaputanaayanayugala Ghranamukhanam Nirodhanam Karyam Suddhasusumnasaranau Sphutamamalah Sruyate Nadah (HP - IV - 68) i.e. Of closing both the ears, both the eyes, both the nostrils and the mouth is practiced, a clear distinct sound is heard in the path of susamna nadi when it is clean.

4. Vipareetakarni Mudra
Refer II Chapter P-15.
5. Yoga Mudra
Refer HI Chapter, P-22.
6. Brahmamu The Name: Brahma is the name of one of the gods of the Hindu trinity, who possesses four heads. Mudra means a symbol.
The Technique: (a) The student sits erect in acomfortable 'asana'. He then turns his head slowly to the right without moving his trunk the chin brought almost in the line with the right shoulder line. The final position is maintained for a few seconds before returning slowly to the starting position.

  1. Then comes a similar movement and pause on the left side.
  2. Returning to the original position, the head is in the same manner
    taken backward, so that the muscles of the throat are stretched to the maximum,
    and again brought to starting position.
  3. This is followed by bending the head forward, chin pressing on the
    jugular notch and again coming to the original position. This completes one
    round of Brahmamudra.

Thus the head is turned to the right, to the left, backward and forward imitating the four heads of Brahma.

Brahma Mudra

Advantages: Brahmamudra, though it looks very simple, is very efficacious for removing psycho-physiological tensions, regulating blood pressure and bring­ing vasomotor tone and also for curing functional disorders of the cervical spine such as stiff neck.
It stimulates the carotid nerve and the carotid arteries which bring supply to the brain.
The cervical spine is turned forward and backward and is twisted. The cervical ganglia and the spinal nerves of the cervical spine are also favourably influenced.
The practice of Brahmamudra gives added advantage when it is accom­panied by two other practices, namely, Jihvabandha and Simhamudra.


_Breathing and Life Process
More than five thousand years ago, the Yogis of ancient India discovered the correlation between the subtle rhythm of breathing and the mind. The "nasal cycle" was not documented in the west until late in the 19th century. Man's lifespan (HR-II-Ch-I) depends on his mode of respiration. A person who breathes in short, quick gasps is likely to have a shorter life than a person who breathes slowly. The ancient munis and Yogis measured a person's lifespan not by years but by the number of his respirations. They considered that everyone is allocated a fixed number of respirations in his or her life time, which differs from person to person. There were no laboratories at that time. Forests and surroundings were the laboratories. The yogis were the scientists and animals their subjects. They investigated and found that animals with slow breathing rate, such as snakes, elephants and tortoises have longer lifespans than animals with fast breathing rates, such as dogs, birds, and rabbits, which live only for a few years. From this observation they realised the importance of slow breathing.

Respiration is directly related to the heart. Slow respiration occurs with a slow beating of heart, and a slow beating heart is conducive to long life. The heart of a mouse beats one thousand times per minute; it has a short lifespan. A whale's heart beat is about sixteen times per minute and an elephant's about twenty five. Both are known for their long lifespans.

Evolution of Pranayama:

Pranayama in Vedas
The evolution of Pranayama is worth mentioning here. The word PRANA is frequently mentioned in Vedas, among which the ATHAR VAVEDA is most important for the study of yoga practices. A Yogi can realise the presence of "CHAKRAS1 within his body which contain nine gates. The description of these eight circles (CHAKRAS) and nine gates (holes) in the human body is clearly given in the ATHAR VAVEDA as follows:
(ATHARVAVEDA - 10-2-31)
PRANA VIDYA is the essence of practical yoga, and a complete sukta has been devoted to the description of the prana in the Atharvaveda. It is mentioned that Prana is the essence of the whole universe. We bow before Prana which controls everything. The different forms of prana are also mentioned in this hymn as Prana and Apana. Further, it is said that all gods worship the Prana. Man takes birth in this world due to prana and can even conceive in the womb due to prana. Past, present and future exist in the pranas. But Pranayama has not been clearly mentioned in the Atharvaveda and further yogangas were also still in the state of growth.
Pranayama in the Brahmanas
With the Brahmanas and the Upanishads, we enter the later vedic age. The Brahmana literature mainly represents the further development of the ritualism of the yajurveda samhitas. Satapatha Brahmana text is affiliated to the sukla yajurveda.
It is stated that desire of mind goes to PRANA, PRANA informa it to VAYU and VAYU tells gods how the man's mind is. At several places, three pranas viz. Prana, apana and vyana have been mentioned. But in a few places, all the five pranas have also been enumerated.
The Brahmanas affiliated to the Samaveda and the Atharvaveda seem to have been composed at a much later date. Amongst the many Brahmanas of the Sama Veda, the Jaiminiya Brahmana (JB) is the oldest and the most important. It contains a good deal of discussion on the PRANA VIDYA.
We come across the concept of the VAGBRAHMA in connection with the recital of various samanas. The unity of S VARA and PRANA has also been emphasized at several places (JB 1.140,164,215 etc.). Here we can find the root of the SVARA concept in the yogic treatise like svarodaya. This Brahmana states that by yoking mind and speech at the time of offering oblations, one can transcendbothbadandgoodactions(JB-i.l6).SHIVASVARODAYA,SWARA CMNTAMANI (by Sveu&etu) and SVARASASTRA MANJARI (by Gana-panardhya, Telugu, 1324-1345 A.D) are important treatises in Swara Yoga. The number of pranas have been mentioned at different place as two three, five, nine and ten.
Pranayama in the Chandogya and Brahdaranyaka Upanishads
The age of the Upanishads was a peak period of Indian thought and yoga forms a very solid part of the same. The term PRANA is used in the UPAN­ISHADS as on excellent concept. Most of the early upanishads have certainly revealed in highest transpsychic yogic state of mind. Among the upanishads, the earliest ones are the CHANDOGYA and BRAHADARANYAKA.
We can find the basis for KRIYAYOGA as also of the YAMAS and NIYAMAS in these two oldest upanishads. There is no specific description of ASANA in these upanishads. But PRANA forms a very important topic of discussion. The Chandogya describes prana, vyana, apana and samana as forming respectively the Eastern, Southers, Western and Northers gates of the heart, whereas UDANA is said to be the upper gate (CU-III-13.1-5).
The different NADIS of the heart have been described in both these upanishads. The colours of these NADIS have also been described. We find here the root of the yogic concept of PINGALA or the SURY A NADI. These are said to be thinner than the thousandth part of a hair. The NADI going to the head is said to be the most important one and it has been declared that one gets immorality going upwards through this NADI. Here, we find the root of the yogic concept of SUSUMNA and KUNDALINI. We do not come across the idea of concentration on the NADIS or vital regions of human body, in these upanishads.

Pranayama in Bhagvad Gita

Amongst the different sections of the Mahabharata dealing with yoga, the oldest and by far the most important one is the famous Bhagvad Gita from the BHISMA PARV AN. This treatise of original GITA of seven hundred and forty five verses has become one of the most important and popular scriptures of the world. It has been estimated that the Mahabharat war commenced in September, 3138 B.C. Pranayama, the next accessor of Patanjali Yoga, has not been described in the Bhagvad Gita in the context of meditation. However, while describing different types of sacrifices in the fourth chapter, the Bhagvad Gita has mentioned two types of practisants of Pranayama. Some practisants suspend exhalation and retain the breath inside. They have been said to offer the oblation of exhaled air (prana) into the inhaled air (apana). The other type of practisants suspend inhalation and retain the exhaled breath outside. These have been described as offering the oblation of inhaled air (apana) into the exhaled (prana). Both of them are said to be devoted to Pranayama. Thus, the Bhagvad Gita seems to have recognised two types of pranayama as two independent means. In the fifth chapter, it has been stated that in the state of meditation, the practisant makes the exhaled and the inhaled airs move inside the nostrils. It may also be looked upon as suspension of breathing, in a way. It may be noted that Pratyahara has been mentioned here before Pranayama. This order has been retained in the Hatha Yoga tradition. Patanjali has altered it. According to him Pratyahara comes after pranayama.

Pranayama in the Puranas

The Kurma Purana
The puranas form a vast literature of Hinduism. Among the eighteen Mahapuranas, the KURMA PURANA and MARKANDEYA PURANA oc­cupy an important place in dealing with Pranayama. The Lord says:
"Those who practise this yoga of mine, twice or thrice a day or all the time, are known to be identified with Mahesvara" (4).
Pranayama is considered to be of three kinds, viz. Superior, middle and low. This again admits of another two fold division viz. With something inside (Sagarbha) and without anything (Agarbha). A Pranayama is called low when it has the duration of twelve moras (Mathas), a midding when the duration is of twenty four moras, and the best when of thirty-six moras. These three kinds of Pranayama cause sweating, trembling and lifting of the body, The Markandeya Purana
The Markendeya Purana is replete with yoga philosopy. In this purana, there is mention of seven stages of yoga practice viz. (1) Vrata, (2) Niyama, (3) Asana, (4) Pranayama (5) Pratyahara, (6) Dharana and (7) Dhyana.
Pranayama is defined as regulation of breath. Just as in the case of metals (like gold and silver) impurites are burnt when they are melted in the furnance, so passions of the organs of sense are destroyed by the control of breath. The control of breath is three-fold: (1) Laghu, (2) Madhyama, (3) Uttama. The time of matra is that of the winking and opening of the eye-lids. Laghu P/anayama of 12 matras, Madhyama of 24, and uttama of 36 matras. This Purana explains how breath is controlled (MKS -38-20).

Pranayama in Sutra Period

 ancient period we find the^ractice of Pranayama m the context of religious rituals. Control of Prana is recommended in the Apasthambha Dharma Sutra 2.5-15(atamitohpranamavacxhet) Breath exhausted (Yavadanganam Glanirbhavati tavatprananayacchet) isthe explana­tion of this sutra by the commentator Haradatta. This position of Pranayama in the Sutra period may be considered to be the first stage in its evoluUon. Sansknt and SansEtic culture appear to have flourished in Andhra areas as early as the Sutra period(600B.C.).P.V.Kane concludes that it is natural to suppose ApasuTambhaschoolhaditsorigioninthesouthprobablyinAndhra. During this
period Pranayama had no independent position. Some Sutra texts prescnbe
mantras was not recognised as an essential technique of Pranayama during the
Sutra period.                         
After the UPANISHADIC scripture, SMRITIS have a great place in Indian culture. There are more than twenty smriitis but MANUSMRITI and BRHADYOGIYAJNAV ALKYASMRITI occupies the foremost place among
Authorities on smriti, like Manu and Yajnavalkya, have described the technique of Pranayama with pranava and Gayatri mantra. Pranayama unac­companied by mantra is not at all acceptable to the Smritikaras. In puranas, however, we get both the varieties of pranayama with and without mantras. Pranayma accompanied by mantras is called "SAGARBHA' and the one unaccompanied by mantras is called 'AGARBHA'. The smritis tried to combine pranayama with the daily rituals. Thus, Pranayma together with Aacamana became part and parcel of every ritual.
Manu lays emphasis on three types ("PRANAYAMAISTRIBHIH PUTASTATAOMIKARAMARHATIA MANUSMRITI (II-75).ofPranayama i.e PURAKA, KUMBHAKA and RECHAKA. According to Manu, prana can purify a person and make him fit for the recitation, OMKARA. Omkara represents the supreme Brahman recited by the yogis. Pranayama is the (PRANAYAMAH PARAM TAPAH (Ibid -11-83) PARAM TAPAS for the highest form of austerity. Both these varieties are of the type of internal retention of the breath. Describption of an external retention of breath is seen in limited texts like Patanjali Yogasutras, yogavasistha etc. Hathayoga texts refer to two types of Kumbhakas, viz. Sahita kumbhaka and Kevala Kumbhaka. Systematic description of the three aspects of PURAKA, KUMBHAKA AND RECHAKA in Pranayama is the special feature of the Hathayogic texts.

Sequence of Pranayama

What should be the sequence of asana and pranayama? The answer to the question is so simple and clear that there is no room for confusion, if we follow the instructions of Atmarama (HP-I-Cha-56) and Srinivasabhatta Mahayogin-dra (HR-I-Ch-16). Atmarama and Srinivasabhatta have clearly said:
"Asanas, different types of Kumbhakas, practices called Mudras, Nada-nussandhana-this is correct sequence for the practice of Hathayoga".
Patanjali has also said:
Tasmin Sati Svasaprasvasyogati Vicchedah Pranayamah"
(PS - II - 49)
i.e. after establishing oneself in a stable posture, Pranayama has to be performed.
There is difference opinion among the Hatha Texts. Gheranda advocates shatkriyas purifies nadis. Brahmananda a well-known commentator onHP, states here that some teachers like Yajnavalkya accepted pranayama to purify the nadis and not shatkriyas (HP-I-ch-38-HR-I-Ch-85).
Basic Unit for Pranayama
According to Adisankara, a yogi attains perfection in pranayama when his nerves are purified. Further it is said that a yogi should make his PRANA subtle while sitting at a place which is pure and clean. The whole atmosphere should be calm, quiet and attractive to the eyes.
But according to Vasistha one should purify one's nadis before commencing pranayama (VS-Ich-81).

At first the Rechaka must be performed by one nostril followeed by the puraka by the same nostril. Then the air should be expelled through the other nostril, and so on. Vasistha names this process not as pranayama but as NADISODHANA. Vasistha gives the correct procedure for the purification of nadis which is controlled inspiration and expiration without kumbhaka. This is the reason we prescribe nadisodhana at the beginning of the yogic practices (Chapter-II-p-8)

Varieties of Pranayama

Pranayamais apause in the movement of breath. In Sanskrit prana means
breath and ayama means a pause. ATMARAMA, the author of HATHAPRAD-IPIKA, and SRINIVASABHATTA MAHAYOGINDRA, the author of HATHARATNAVALI both authoritative textbooks on Hatha yoga, mention eight and nine varieties of Kumbhakas respectively. They are Suryabhedana, Ujjayi, Sitkari, Sitali, Bhastrika, Bhrameri, Murccha, Plavani and Bhujangee-karana. Kumbhaka is another name for pranayama in Hathayoga. The technique of all the eight or nine kumbhakas is the same. But the technique of inhalations and exhalations differ is every case. Each round of Pranayama is generally a complex act and consists of PURAKA (inhalation), RECHAKA (exhalation), KUMBHAKA (pause), and SUNYAKA (holding without air) The duration in pranayama should be judged mentally. The mind should very closely follow the movement of breath. The aim of all types of Pranayama is to work up the dormant kundali. Influence of Seasons and Geographical Conditions
During different seasons of the year, the dhatus undergo certain changes. If certain precautionary measures are not taken during these seasons, the person would be exposed to disease. Geographical locations also exert certain influence on the individuals. The Himalayan range is distinctively cold and the plains are distinctively warm. They have an influence on prakriti and yogic practices. Seasons are considered, particularly in the selection of "PRANAYAMA'. Brahmananda (1830 A.D) adisciple of Merusastry, the authoritative commentator on HP, attributes cause not only to seasons, but also to individuals's nature, i.e. he develops the tridosha concept. He further says in Jyosna (HP-II-66) that Suryabedhana and Ujjayi generate heat, while Sitali and Sitakari are cool. Bhastrika preserves an equable temperature. Suryabedhana primarily controls excess of wind, Ujjayi phlegm, Sitakari and Sitali bile, and Bhastrika all three. Suryabedhana Pranena Vataharam. Ujjayi pranena slesmaharah. Sitkari Sitalyo pranena pittahara. Bhastrakhyah kumbhakah tridoshahara it bodhyam.
Oxygen value versus nerve culture of Pranayama
Recently, this nasal cycle has re-emerged as a promising focus of scientific research. We are conducting a number of experiments in our most sophisticated laboratory of our Institute on the oxygen value of Pranayama for the past one decade.
The westerner takes to exercise in deep breathing mainly from the point of view of its oxygen value. He appreciates these exercises mainly because they give him a larger quantity of oxygen to vitalise his system with us the oxygen value of Pranayama is subordinate. We value it more for its nerve culture. The effects of pranayama is more on the nervous system than on the lungs. The practice of Pranayama helps to clean the "NADIS'. The purpose of pranayama is to make the respiratory system function at its best. This automatically improves the circulatory system, without which the processes of digestion and elimination would suffer. The respiratory system is the gateway to the purification of the body, mind and intellect. The key to this is Pranayama.
Respiration may be classified into four types (a) High or clavicular breathing, where the relevant muscles in the neck mainly activate the top parts of the lungs, (b) Intercostal or midbreathing, where only the central parts of the lungs are activated (c) Low or diaphramatic breathing, where the lower portions of the lungs are activated chiefly, while the top and central portions remain less active and (d) Total or Pranayamaic breathing in which the entire lungs are used to their fullest capactiy.
In concluding this short introductory chapter on Pranayama, we have to point out to our reader that the subject is very vast and requires a lot of information for its full practice. Pranayama is a weapon that easily lends itself to abuse. Yoga texts caution against wrong ways of practising pranayama (HP-II-Cha-16-HR-cha-III-92). In practising Pranayama a man plays with his nerves, heart and lungs.
Extra strain or improper methods in pranayama may damage and harm these delicate parts of the body. So every practitioner should do this practice with due caution and care. Now we will briefly describe a few easy and common pranayamas.

Ujjayi (Hissing Pranayama)

Explanation : The prefix "UD" means upwards or expanding; "JAYA" means conquest or success. "UJ J A Y A1 a variant reading noticed by Brahmananda in his commentary on HP, actually means "pronounced loudly". Ujjayi might be interpreted to mean leading to success. Ujjayi is that which is sonorous. Technique: Sit in Dhyanasana.. Close the eyes. Breathe in and out through both nostrils. Do chest breathing. While breathing in, keep the chest expanded and close the glottis partially. This partial closure of the glottis will produce a continous sound like the sound that is produced in sobbing. The difference is that in sobbing the sound is abrupt and borken. Here it is continuous. At the time of inhalation the facial muscles or the muscles of the nose should not be contracted. As a result, there is a noise from the throat with every breath. The amount of air exhaled is more than that inhaled. The eyes must focus on the tip of the nose. Release the lock by raising the head back and exhale slowly. Hold the breath out as long as you comfortably can. Rechaka is to be done through the left nostril. The time proportion between puraka, kumbhaka and rechaka is 1:2:2. The glottis should all along remain partially closed and then released. This completes one cycle. Again it is repeated. What is the orthodox way of closing the nostrils in yoga?

Preparation for closing of nostril

For closing the nose during kumbhaka, the use of fingers except the index and middle fingers seems to belong to Hathayogic and tantric tradition. Smriti's allow the use of all the 5 fingers during pranayama practice for closing the nose.
The right palm is spread out, the index and the middle fingers are turned down, the other two fingers and the thumb remain extended (vide fig.). Now the thumb and the extended fingers and placed on the bridge of the nose, the thumb
on the right side of it, and the fingers on the left.
Equation of Ujjayi
Benefits : Ujjayi removes from the throat diseases caused by phlegm (slesma dosa haram) and increases the gastric fire. It has a soothing effect on the nervous system and calms the mind. This practice is also good for low blood pressure, asthma and depression.
Caution :
The airway resistance at the palate is the important aspect of this

Surya Bedana Pranayama

In Suryabedhana Pranayama all inhalations are done through the right nostril and all exhalations through the left.
Explanation : In Hatha yoga literature Surya means the right and Chandra means the left. Bhid, the root of bhedana, means to pierce, or pass through. Another meaning of Bhedhana is activity.
Sit in a comfortable meditation pose preferably in Vajrasana. Raise the right hand, placing the middle and index fingers on the forehead and the thumb and the ring finger gently on each side of the nose.
Close the left nostril with the ring finger and inhale deeply through the right nostril. Close both hostrils, retain the breath and perform Bhandhas. Maintain according to your own capacity. Release Moola and them Jalandhara Bandhas.
Exhale through the right nostril by keeping the left nostril closed. This is followed by uddiyana Bandha. This is one round. Repeat the same process. EQUATION OF SURYABEDANA: Draw the air through the right nostril + Kumbhaka and exhale only through the left nostril. Benefits: This Pranayama activates SUR Y AN ADI (right side of the nostril) and therefore, increases heat in the body and digestive power. It controls the VATA DOSHA. It is also good for persons suffering from low blood pressure. Caution : Do not perform Surya Bhedana and Chandra Bhedana or Sitali or Sitkari pranayama at the same sitting.

Chandra Bhedana Pranayama

Explanation : The explanation is given in the above pranayama. Source : This Pranayama has been described in YOGA CHUDAMANI UPANISHAD (95-97) without mentioning the name Chandra bedhana, but giving only the method.
The name and full technique of Chandrabhedana, Pranayama is de­ scribed in the "ORIGINAL HATHAPRADIPIKA" (M.S) (IV-Cha-54 to 60) Technique : Follow the same techniques as are given in all the stages of Suryabedhana, reading the word "right" for "left" and viceversa. Equation of Chandrabhedana : Draw the air through the left nostril + Kumbhaka and exhale only through the right nostril. Benefits: This Pranayama activates CHANDRANADI (left side of the nostril) and therefore, increases cool in the body. It controls the PITTA DOSHA. It is also good for persons suffering from the early stages of high blood pressure. Caution: Do not perform Chandrabedhana and Suryabhedana Pranayama at the same sitting.

Bhramari Pranayama

Explanation: "BHRAMARI" is the feminine form of "BHRAMARA" meaning a bee. This kumbhaka is called BHRAMARI because its technique requires the
production of a sound resembling that of a bee both in puraka and Rechaka. Technique : Sit erect in a comfortable meditative posture, keep the mouth closed throughout the practice; inhale (puraka) deeply through both nostrils.
It will be found that the palate is lifted and drawn towards the nasal part of the pharynx. This movement can be made closer and closer to the pharynx, and inhale. A beautiful sound produced by a combination of the gentle vibrations of the soft plate and the nasal friction will be heard. Retain the breath inside and perform jalandhara and moola bhandas.
Slowly exhale (Rechaka) while producing a sound from the mouth and nose, So as to produce a sweet musical humming sound like a female bee. S lowly release. Repeat the cycle several times.
Equation of Bhramari: Inhale air through both the nostrils + Kumbhaka + exhale producing a sound from mouth and nose.
Benefits : Relieves cerebral tensions removes anxiety and stress and reduces blood pressure. Eliminates ENT disorders and creates awareness of NADA. Caution : Do not practise Kumbhaka phase in case of high B.P and heart ailments without consulting yoga experts.
Variation : Gheranda Samhita in V_Cha-77-88 gives another technique (plug both ears with index fingers) and SHIVA SAMHITA in V ch-39 to 48 describe yet another under the name of Rajayoga i.e. Sanmukhi Mudra (refer-cha-IV-9)

Sitali Pranayama

Explanation : The name of this Pranayama is derived from its cooling effect on the body. SITALI is the feminine form of SITAL meaning cool. This pranayama cools the dystem; hence the name. Technique : Sit in any confortable meditative posture.
Keep the spine erect, and close the nostril with the right hand. Open the mouth and form the lips into an 0 shape. Push out the tongue and folding about 3/4 of an inch outside the lips. This lingual channel is to be used for inhaling air from outside at the time of puraka. In this pranayama inhalation is done through the mouth and not through the nostrils. After inhalation, the tongue is to be withdrawn and lipsare to be closed. Kumbhaka is of the usual type. Rechaka is to be done slowly as in other cases, but through both the nostrils at the same time. Repeat the cycle.
Equation of sitali: Drawn the air through the (folding tongue) through mouth + Kumbhaka and exhale air through both the nostrils. Note : Kakacanch (Shiva Samhita -111-84) is the tongue folded like a crow's beak.

The Tongue arranged as Birds Beak

Explanation : "SITKAR" means the sound "SEET" AND SITAKARI means the pranayama in which the sound "SEET" is produced. Technique : Follow the same techniques as are given in all the stage of "SITALI", reading the word "FOLDING-TONGUE" for "Teeth".
Press the upper teeth on the lower ones. Suck in air through the crevices of the teeth slowly steadily and continously. There is no reference to Kumbhaka. But the authors of HP and HR has included Sitkari in the list of kumbhakas. So to say kumbhaka is of the usual type and exhale through both the nostrils. Equation of Sitkari : Draw the air through the mouth (pressing teeth) + Kumbhaka + and exhale air through both the nostrils. Benefits: These are cooling pranayamas. They cool the system and smooth the eyes and ears. They are beneficial in cases of low fever. They activate the liver and spleen, improve degistion and relieve thirst. They also help in calming down the mind by removing mental anxiety and tension. These two pranayamas may be done by the practitioner, even when the nostrils are blocked. Traditional texts suggest pranayamas may be done by the practitioner, even when the nostrils are blocked. Traditional texts suggest pranayamas control the "PITTADHOSA" (bile)

As the world's population grows, the need for health care increase. In recent years progress in medical care has been rapid, especially in such fields as neurology and cardiology. A major reason for this progress has been the marriage of two important disciplines: medicine and engineering. The problem of biomedical engineering involves communication between the engineer and the medical profession.
The branch of science that includes the measurement of physiological variables and parameters is known as BIOMETRICS. Biomedical instruments provide the tools by which these measurements can be achieved.
The basic objectives of any instrumentation system generally fall into one of the following major categories:
