“The purpose of Āsana and Prāṇāyāma are twofold,
to reduce symptoms of ill-health or,
to prepare the mind towards fulfilling the
main emphasis of Patañjali, which is Meditation.
However according to the teaching I have received,
both of these roles can be fulfilled with relatively
few Āsana postures and Prāṇāyāma techniques.”
– TKV Desikachar on Yoga Sūtra Chapter Two verse 28
