Commentaries and Reflections

Commentary by TKV Desikachar:

“Its the combination (of Guṇa) thats important.
There is the simile of the oil lamp in the Sāṃkhya Kārikā Śloka 13.
The cotton wick – Light Property (Sattva)
The basin or bowl – Heavy Property (Tamas)
The oil – Flows this way or that (Rajas)
The moment you dip the cotton in the oil it takes on that property.
Thus the Guṇa work together to produce the flame.”
– TKV Desikachar Madras November 24th 1979 on Sāṃkhya and Yoga
