5.15.2

atsy annaṃ paśyasi priyam \
atty annaṃ paśyati priyaṃ bhavaty asya brahmavarcasaṃ kule ya etam evam ātmānaṃ vaiśvānaram upāste \
saṃdehas tv eṣa ātmana iti hovāca \
saṃdehas te vyaśīryad yan māṃ nāgamiṣya iti \\515.2\

2. You eat food; you see what is pleasing. He eats food; he sees what is pleasing. There is eminence in sacred knowledge in the family of him who reverences that Universal Ātman (Soul) thus. That, however, is only the body (_saṃdeha_) of the Ātman (Soul),’ said he. ‘Your body would have fallen to pieces, if you had not come unto me.’
