Bhagavad Gita
13.31

यदा भूतपृथग्भावमेकस्थमनुपश्यति । तत एव च विस्तारं ब्रह्म सम्पद्यते तदा ॥

yadā bhūtapṛthagbhāvamekasthamanupaśyati | tata eva ca vistāraṃ brahma sampādyate tadā ||

Translation

When one sees the separate existence of all beings resting in one — and from that same one, the expansion — then one becomes Brahman.

Interpretation

The moment of liberation described: when one sees (anupdashyati — continuously perceives, not just once) that bhuta-prithak-bhavam (the separate existence of all beings — the apparent diversity of all individual creatures) rests in ekastham (the one ground, the single Divine base), and from that same one comes the vistara (expansion into multiplicity) — at that moment brahma sampadyate — 'one becomes Brahman.' Becomes, not merely knows about. The recognition of unity-in-diversity and diversity-in-unity is the direct experience of Brahman.
