In plain words
Then Uṣasta, Cakra's descendant, put his question. "Yājñavalkya," he said, "tell me of the brahman that stands directly before us, hidden from nothing -- the self that lives inside everything. Explain it to me plainly." "This very thing is your self, the one inside everything." "But which one is that, Yājñavalkya -- which is the one inside everything?" "The one who breathes out through the out-breath -- that is your self, inside everything. The one who breathes down through the down-breath -- that is your self, inside everything. The one who breathes evenly through the pervading breath -- that is your self, inside everything. The one who breathes up through the up-breath -- that is your self, inside everything. This is your self, the one inside everything."

Then indeed Uṣasta Cākrāyaṇa questioned him. "Yājñavalkya," he said, "that brahman which is directly present, not hidden from perception, the self that is within all -- explain that to me." "This is your self, the one within all." "Which one, Yājñavalkya, is the one within all?" "He who breathes forth by the out-breath, he is your self, the one within all. He who breathes down and out by the down-breath, he is your self, the one within all. He who breathes through by the diffused breath, he is your self, the one within all. He who breathes up by the up-breath, he is your self, the one within all. This is your self, the one within all."
