Commentaries and Reflections

Commentary by S Ramaswami:

“This Sūtra indicates the Sāmkhya principles of evolution. The stages of evolution of the Guṇa.

First Sattva (Mahat) then Rajoguṇa (Ahaṃkāra), then Sattva Ahaṃkāra, the ten Indriya plus Manas, and Tamo Ahaṃkāra, the Five Tanmātra and the Five Bhūta.
i.e.

Aliṅga (AVYAKTA)
Liṅga (Sattva) (VYAKTA)
Ahaṃkāra (RAJAS)

SATTVA AHAṂKĀRA – TAMAS AHAṂKĀRA

KARMA INDRIYA/JÑĀNA INDRIYA/MANAS – TANMĀTRA/MAHĀBHŪTA
