Breath Control or Pranayama

School of Yoga explains Pranayama;

In Classical Yoga, Pranayama means controlling the breathing process. Here, pranayama means Prana = breath of life + yama = control.

Pranayama is a natural progression of asanas. Consequently, the various techniques of pranayama are generally taught with asanas. School of Yoga considers proper practice of pranayama to be as important as practice of asanas.

Classical yoga defines Pranayama or breath control

The Hatha Yoga Pradeepika has a complete chapter on Pranayama… 

Chapter 2 of Hatha Yoga Pradeepika says:

  1. Once a yogi has perfected asanas, he should maintain a beneficial and moderate diet and practice pranayama as instructed by his Guru.
  2. When the breath is disturbed, the mind becomes disturbed. When the breath is still, so is the mind.
  3. For as long as there is prana in the body, there is life. Death occurs when prana leaves the body, hence the need to restrain it.
  4. Owing to impurities in the nadis, the prana does not pass through the middle channel. So how can one achieve the state of the precious gem (unmani)? How does one achieve siddhi?
  5. When all the nadi’s are cleansed, then the yogi is able to restrain the breath.
