Bhagavad Gita, Chapter 6, Verse 29

With the heart concentrated by Yoga, with the eye of evenness for all things, he beholds the Self in all beings and all beings in the Self.

Once that connection is real, everyone starts looking like part of the same larger picture, not separate from it.

This extends the earlier equal-vision teaching into something even more specific. Not just fairness between people, but genuinely seeing the same divine presence running through every single one of them.
