Bhagavad Gita, Chapter 5, Verse 19

Even here, those have conquered the material world, whose mind rests in evenness; since Brahman is even and without imperfection, therefore they indeed rest in Brahman.

That kind of equal vision isn't just a nice ideal, it's described as something that genuinely changes a person's whole situation, right now.

This isn't deferred to some future reward, it's framed as immediately real. Someone who's actually reached that equal way of seeing is described as already free in a meaningful sense, not waiting for it later.
