“In Veda, Āyurveda and Yoga Sūtra,
various techniques are offered to aid in healing the sick.
In addition to herbs and medicines,
Patañjali suggests that Āsana, Prāṇāyāma and Vairāgya
are particularly beneficial and, as any medicine,
should be used with care and discipline.”
– T Krishnamacharya’s commentary to Yoga Sūtra Chapter One verse 34
