Svara Sadhana, practice of breath, is the revealer of Satya, Brahman and bestower of the Supreme Knowledge and Bliss. Perform calm acts during the flow of Ida and harsh acts during the flow of Pingala. Do acts resulting in the attainment of psychic powers, Yoga, meditation, etc., during the flow of the Sushumna. If the breath rises by Ida (moon) at sunrise and flows throughout the day, and Pingala (sun) rises at sunset and flows throughout the night it confers considerable good results. Let the breath flow through Ida the whole day and through Pingala the whole night. He who practises thus is verily a great Yogi.

How To Change The Flow In Nadis The following exercises are for changing the flow from Ida to Pingala. Select any one of the methods that suits you best. For changing the flow from Pingala to Ida, just do the same exercise on the opposite side:

1. Plug the left nostril with a small piece of cotton or fine cloth for a few minutes.

2. Lie down on the left side for ten minutes.

3. Sit erect. Draw the left knee up and keep the left heel near the left buttock. Now press the left arm-pit, Axilla, on the knee. In a few seconds the flow will be through Pingala.

4. Keep the two heels together near the right buttock. The right knee will be over the left knee. Keep the left palm on the ground a foot away and let the weight of the trunk rest on the left hand. Do not bend at the elbow. Turn the head also towards the left side. This is an effective method. Catch hold of the left ankle with the right hand.

5. The flow of breath can be changed by Nauli Kriya also.

6. There are some who are able to change the flow by will.

7. Place the Yoga Danda or Hamsa Danda (a wooden stick of about 2 feet in length with a rest of the shape of U at one end) at the left arm-pit and lean on it by the left side.

8. The most effective and instantaneous result is produced in changing the flow through Khechari Mudra. The Yogi turns the tongue inside and blocks the air passage by the tip of the tongue.

The above exercise is intended for general regulation of breath. Many other special exercises for the purification of Nadis and awakening Kundalini will be given in the subsequent chapters. A knowledge more secret than the science of breath, a friend more true than the science of breath, has never been seen or heard of. Friends are brought together by the power of breath. Wealth is obtained with comfort and reputation through the power of breath. The knowledge of the past, present and the future and all other Siddhis are acquired and a man reaches the highest state, by the power of breath.

I want you to practise every day the Svara Sadhana systematically and regularly, that is, to allow the flow of breath through the left nostril throughout the day and through the right nostril throughout the night. This will, doubtless, bestow on you wonderful benefits. Wrong Svara is the cause of a host of ailments. Observance of right Svara as described above leads to health and long life. Verily, verily, I say this unto you, my dear children! Practise this. Practise this from today. Shake off your habitual sloth, indolence and inertia. Leave off your idle talk. Do something practical. Before you begin the practice, pray to Lord Siva, who is the giver of this wonderful science by uttering Om Namah Sivaya and Sri Ganesha, the remover of all obstacles.
