I am all This, and all This is Yours, O Lord!

I am all This (when there is no thought) and all This is Yours O Lord (when there is thought). And thought too is nothing but the Self. Only the Self Is. He who understands this in truth, understands advaita and dvaita. Yea, he truly understands! Established in that Truth he seemingly engages in actions as the wise did of old, vigatajvarah (free of fever). See also Bhagavad GItA.
