Bhagavad Gita Chapter 7, Verse 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 source in these two natures. I am the source and dissolution of the entire world.

Krishna now reveals His ultimate nature: the source of everything. 'Etad yonīni bhūtāni sarvāṇi'—all beings have their source in these two natures (material and spiritual). 'Ahaṁ kṛtsnasya jagataḥ prabhavaḥ pralayas tathā'—I am the source (prabhava) and dissolution (pralaya) of the entire world. Everything comes from Krishna and returns to Krishna. This verse establishes Krishna as the ultimate source—not just a part of reality, but the source of all reality. Both material and spiritual natures come from Him. This is the culmination of the revelation: Krishna is the source of everything.
