This course is a must for everyone to realize how important proper breathing is.
I recently happened to do the basic course in haridwar and at first I felt that it was utter stupidity to waste 2 hours daily for a week an attending the course but after completing the one weeks course I realized how good it was.
The course is well designed and handled by experienced teachers who have learnt the stuff very well.
The course teaches many thing apart from breathing...
