Then Ushasta Kâkrâyana asked. 'Yâgñavalkya,' he said, 'tell me the Brahman which is visible, not invisible , the Self (âtman), who is within all.' Yâgñavalkya replied: 'This, thy Self, who is within all.' 'Which Self, O Yâgñavalkya, is within all?' Yâgñavalkya replied: 'He who breathes in the up-breathing, he is thy Self, and within all. He who breathes in the down-breathing, he is thy Self, and within all. He who breathes in the on-breathing, he is thy Self, and within all. He who breathes in the out-breathing, he is thy Self, and within all. This is thy Self, who is within all.'
