Bhagavad Gita · 7.6

एतद्योनीनि भूतानि सर्वाणीत्युपधारय।अहं कृत्स्नस्य जगतः प्रभवः प्रलयस्तथा॥

etad-yonīni bhūtāni sarvāṇīty upadhāraya ahaṁ kṛtsnasya jagataḥ prabhavaḥ pralayas tathā

Know that all beings have their origin in these two natures. I am the source of the entire creation and also its dissolution.
