Sitali
Protrude the tongue a little away from the lips. Fold the tongue like a tube. Draw in the air through the mouth with the hissing sound Si. Retain the breath as long as you can hold on with comfort. Then exhale slowly through both nostrils. Practise this daily again and again in the morning from 15 to 30 times. You can do this either on Padmasana, Siddhasana, Vajrasana or even when you stand or walk.
This Pranayama purifies the blood. It quenches thirst and appeases hunger. It cools the system. It destroys Gulma (chronic dyspepsia), Pleeha, inflammation of various chronic diseases, fever, consumption, indigestion, bilious disorders, phlegm, the bad effects of poison, snake-bite, etc. When you are caught up in a jungle or any place where you cannot get water, if you feel thirsty, practise this Pranayama. You will be at once relieved of thirst. He who practises this Pranayama regularly, will not be affected by the bite of serpents and scorpions. Sitali Kumbhaka is an imitation of the respiration of a serpent. The practitioner gets the power of casting his skin and enduring the privation of air, water and food. He becomes a proof against all sorts of inflammations and fever.
Bhastrika
In Sanskrit Bhastrika means ‘bellows’. Rapid succession of forcible expulsion is a characteristic feature of Bhastrika. Just as a blacksmith blows his bellows rapidly, so also you should move your breath rapidly.
Sit on Padmasana. Keep the body, neck and head erect. Close the mouth. Next, inhale and exhale quickly ten times like the bellows of the blacksmith. Constantly dilate and contract. When you practise this Pranayama a hissing sound is produced. The practitioner should start with rapid expulsions of breath following one another in rapid succession. When the required number of expulsions, say ten for a round, is finished, the final expulsion is followed by a deepest possible inhalation. The breath is suspended as long as it could be done with comfort. Then deepest possible exhalation is done very slowly. The end of this deep exhalation completes one round of Bhastrika. Rest a while after one round is over by taking a few normal breaths. This will give you relief and make you fit for starting the second round. Do three rounds daily in the morning. You can do another three rounds in the evening also. Busy people who find it difficult to do three rounds of Bhastrika can do one round at least. This also will keep them quite fit.
Bhastrika is a powerful exercise. A combination of Kapalabhati and Ujjayi makes up Bhastrika. Practise Kapalabhati and Ujjayi to start with. Then you will find it very easy to do Bhastrika.
Some prolong the practice till they get tired. You will get perspiration profusely. If you experience any giddiness stop the practice and take a few normal breaths. Continue the practice after the giddiness has vanished. Bhastrika can be done both in the morning and evening in winter. In summer do it in the morning only during cool hours.
Bhastrika relieves inflammation of the throat, increases gastric fire, destroys phlegm, removes diseases of the nose and chest and eradicates asthma, consumption, etc. It gives good appetite. It breaks the three Granthis or knots viz., Brahma Granthi, Vishnu Granthi and Rudra Granthi. It destroys phlegm which is the bolt or obstacle to the door at the mouth of Brahma Nadi (Sushumna). It enables one to know the Kundalini. It removes all diseases which arise from excess of wind, bile and phlegm. It gives warmth to the body. When you have no sufficient warm clothing in a cool region to protect yourself from cold, practise this Pranayama and you will get sufficient warmth in the body quickly. It purifies the Nadis considerably. It is the most beneficial of all Kumbhakas. Bhastrika Kumbhaka should be specially practised as it enables the Prana to break through the three Granthis or knots that are firmly located in the Sushumna. It awakens the Kundalini quickly. The practitioner will never suffer from any disease. He will always be healthy.
The number of exhalations or rounds is determined by the strength and capacity of the practitioner. You must not go to extremes. Some students do six rounds. Some do twelve also.
You can practise Bhastrika in the following manner. There is some slight change in the end. Having inhaled and exhaled quickly twenty times, inhale through the right nostril, retain the breath as long as you can do it comfortably and then exhale through the left nostril. Then inhale through the left nostril, retain the breath as before and then exhale through the right nostril.
Repeat OM mentally with Bhava and meaning throughout the practice.
There are some varieties of Bhastrika wherein one nostril only is used for breathing purposes and in another variety the alternate nostrils are used for inhalation and exhalation.
Those who wish to do Bhastrika for a long time in an intense manner should live on Khichdi, and take an enema or do Bhasti in the morning before starting the practice.
Bhramari
Sit on Padmasana or Siddhasana. Inhale rapidly through both nostrils making sound of Bhramara, the bee, and exhale rapidly through both nostrils, making the humming sound.
You can carry the process till the body is bathed in perspiration. In the end inhale through both nostrils, retain the breath as long as you can do it comfortably and then exhale slowly through both nostrils. The joy which the practitioner gets in making the Kumbhaka is unlimited and indescribable. In the beginning, heat of the body is increased as the circulation of blood is quickened. In the end the body-heat is decreased by perspiration. By success in this Bhramari Kumbhaka the Yogic student gets success in Samadhi.
Murchha
Sit in your Asana and inhale. Retain the breath. Do Jalandhara Bandha by pressing the chin against the chest. Retain the breath till you expect fainting and then exhale slowly. This is Murchha Kumbhaka as it makes the mind senseless and gives happiness. But this is not suitable for many.
Murcha Pranayama
Plavini
Practice of this Pranayama demands skill on the part of the student. He who practises this Plavini can do Jalastambha (solidification of water) and float on water for any length of time. Mr. ‘S’ a Yogic student can float on water for twelve hours at a stretch. He who practises this Plavini Kumbhaka can live on air and dispense with food for some days. The student actually drinks air like water slowly and sends it to the stomach. The stomach gets bloated a bit. If you tap the stomach when it is filled with air, you will get a peculiar tympanic (air) sound. Gradual practice is necessary. The help of one who is well versed in this Pranayama is also necessary. The student can expel all the air from the stomach by gradual belching.
