He is the truth. He is the self-supreme. You are that, shiveta ketu, you are that. And this last verse is referring, it's in this Chandogya Upanishad, it's a conversation between the teacher and his son, and the son is shiveta ketu, my apologies for pronunciation. So once he's saying that these rivers is an analogy for you and I, and we might see ourselves as different, but at some point we will flow and become one with the ocean. And he's pointing out to his son, you are not different from that. You, yourself, you are atman.
