Translation
When he perceiveth the diversified existence of beings as rooted in One, and spreading forth from it, then he reacheth the Eternal
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
A shift from the self’s non-agency to a unity claim: seeing the diversified existence of beings as rooted in a single source, and as spreading forth from it, is what leads to Brahman. It’s the positive complement to verse 30 — not just “the self doesn’t act,” but “the multiplicity of selves and things is itself grounded in one thing” — bringing the chapter’s dualist prakriti/purusha language back toward the non-dual note verse 13 opened on.
