Bhagavad Gita 7.6 — Origin and end of all
एतद्योनीनि भूतानि सर्वाणीत्युपधारय। अहं कृत्स्नस्य जगतः प्रभवः प्रलयस्तथा ॥
etadyonīni bhūtāni sarvāṇītyupadhāraya | ahaṃ kṛtsnasya jagataḥ prabhavaḥ pralayastathā ||
Meaning
Understand that all beings arise from these two natures. I am the origin of the whole universe and also its dissolution.
