Bhagavad Gita - Verse by Verse - Verses 13.31 - 13.35 - Session 103

When one sees The Self in every being and every being in The self, then that Jnani becomes one with The Self.

Just as the all pervading space is not affected due to its subtlety, The Self too which is present in every being is unaffected.
Just as one Sun illuminates the entire world, one Kshetrajna illuminates the entire Kshetram. Those who can discern Kshetrajna from Kshetram and abide to Kshetrajna will attain the supreme.
