Yoga Sutras 2.49-2.53
"Pranayama is the regulation of the incoming and outgoing flow of breath with retention. It is to be practiced only after perfection in asana is attained. Pranayama has three movements: prolonged and fine inhalation, exhalation and retention; all regulated with precision according to duration and place. The fourth type of pranayama transcends the external and internal pranayamas, and appears effortless and non-deliberate. Pranayama is not only an instrument to steady the mind, but also the gateway to concentration, dharana."-translation by B.K.S. Iyengar
Breath…I have so much to say about breath that not many words comes out. The more I feel about the importance of something, the harder it is for me to say something coherent about it.
During most of the day, most of the time, I think most people rarely take a single full breath. It’s the source of our energy and we sip at it.
If we do nothing else, as yogis and yoginis, let’s teach the world to breathe. It could change everything.
