B.G 13.20
Understand that both 'Prakrti', i.e. insentient and the 'Puruṣa' are without beginning; know that distortions and qualities are indeed born of 'Prakrti'.
Gīta Bhāshya 13.20
The statement summarizes the Prakrti, i.e. insentient, its distortions, and the being. Subtle distortions in three qualities at the time of cosmic creation manifest into action and inaction.
The statement summarizes the Prakrti, i.e. insentient, its distortions, and the being by the verse 'prakṛtiṃ' modifications, and persons by saying 'nature'.
The qualities such as sattva and others have very little distinct variation between dissolution and creation; thus, their distortions are mentioned separately.
"The action and inaction arise in people with subtle variances in the three qualities."
-stated thus in the branch of Madhucchandas (Vedic testimonial).
