Commentaries and Reflections

Commentary by TKV Desikachar:

Sāṃkhya will not make sense to those people who have not tried anything.
i.e. Prayer, Mantra, Medicine.”
– TKV Desikachar Madras November 24th 1979 on Sāṃkhya and Yoga

Commentary by Paul Harvey:

“Within and around us is an absence of certainty and permanence.”
