“Among the disciplines to be applied are:
– Using appropriate breathing technique when moving the body in Āsana practice.
– Eliminating unnecessary travel.
– Regulating the intake of food.
Without these disciplines, the practice of Āsana, Prāṇāyāma and Vairāgya will not be effective.”
– T Krishnamacharya’s commentary to Yoga Sūtra Chapter One verse 34
