Bhagavad Gita 11.13

तत्रैकस्थं जगत्कृत्स्नं प्रविभक्तमनेकधा।अपश्यद्देवदेवस्य शरीरे पाण्डवस्तदा॥

tatraikasthaṃ jagatkṛtsnaṃ pravibhaktamanekadhā |apaśyaddevadevasya śarīre pāṇḍavastadā ||

There, in the body of the God of gods, Arjuna then saw the entire universe resting in one, with its myriad of divisions.

In that vision, Arjuna saw the universe, with its manifold shapes, all embraced in one, its Supreme Lord.

Our plain-language meaning of this verse is waiting for scholar review.
