Bhagavad Gita, Chapter 13, Verse 31

When he sees the separate existence of all beings inherent in the One, and their expansion from That One alone, he then becomes Brahman.

Real, obvious differences between living beings are shown here resting on one shared, common root underneath.

Recognizing that every kind of being still comes from the same material nature is named as the real path to realizing Brahman. Surface variety and underlying unity are held together, not treated as contradictions.
