Bhagavad Gita · 10.39

यच्चापि सर्वभूतानां बीजं तदहमर्जुन।न तदस्ति विना यत्स्यान्मया भूतं चराचरम्॥

yach chāpi sarva-bhūtānāṁ bījaṁ tad aham arjuna na tad asti vinā yat syān mayā bhūtaṁ charācharam

Moreover, I am the seed of all beings, O Arjuna. There is no being — moving or non-moving — that can exist without me.
