And thank you Frederic, for looking into this practice. So simple yet deeply effective- it's good to know for oneself that it doesn't always take a lot of time to change one's state. Warmest wishes.
I just call that one "Hissing Breath" because it was not invented by a yogi, but by a woman in teh1940's or 50's who was teaching body awareness to dancers and actors. It was meant to release holding in the diaphragm. I found that it has a very grounding and calming influence on the whole system. I think Richard Rosen, also on Yoga Anytime, talks about this one, and I know he mentions it in one of his pranayama books. Thank you for your interest! Love, Patricia
