“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

“The moon,
whose rays are auspicious for the gathering of medicinal herbs,
is the god of herbs,
whilst the light of the sun gets to the bottom of all impurities.
This is why we recite Mantra to these two stars,
during the preparation of Āyurveda remedies.”
– T Krishnamacharya

“Sāṃkhya will not make sense to
those people who have not tried anything.
i.e. Prayer, Mantra, Medicine.”
– TKV Desikachar on Sāṃkhya and Yoga
