B.G 7.06

etadyonīni bhūtāni sarvāṇītyupadhāraya। ahaṁ kr̥tsnasya jagataḥ prabhavaḥ pralayastathā ॥6॥

Understand this entire Prakrti to be the womb of all creatures. But I am the cause of its origin and likewise its dissolution.

Gīta Tātparya 7.06

Sentient prakrti is Lakshmi, while insentient Prakrti is made up of three qualities (sattva, rajas, tamas). Propelled by the power of lord Vishnu, she alone is considered the material cause of the universe.

"acetanā cetaneti dvividhā prakr̥tirmatā। triguṇā'cetanā tatra cetanā śrīrharipriyā॥ te ubhe viṣṇuvaśage jagataḥ kāraṇe mate। pitā viṣṇuḥ sa jagato mātā śrīryā tvacetanā। upādānaṁ tu jagataḥ saiva viṣṇubaleritā॥"

"Nature (Prakriti) is considered to be of two types: insentient (acetana) and sentient (cetanā). The insentient is of three qualities (sattva, rajas, tamas), while the sentient is Lakshmi, beloved of Hari (Vishnu). Both these aspects are under the control of Vishnu and are considered the cause of the universe. Vishnu is the father of the world, and Lakshmi, representing the insentient, is its mother. She alone, propelled by the power of Vishnu, is considered the material cause of the universe."
