Chandogya Upanishad 5.17

5.17.1

atha hovācoddālakam āruṇim \
gautama kaṃ tvam ātmānam upassa iti \
pṛthivīm eva bhagavo rājann iti hovāca \
eṣa vai pratiṣṭhātmā vaiśvānaro yaṃ tvam ātmānam upāsse \
tasmāt tvaṃ pratiṣṭhito 'si prajayā ca paśubhiś ca \\517.1\

1. Then he said to Uddālaka Āruṇi: ‘Gautama! Whom do you reverence as the Ātman (Soul)?’

‘The earth indeed, Sir, O King,’ said he.

‘The Universal Ātman (Soul) is, verily, that support, which you reverence as the Ātman (Soul). Therefore you are supported with offspring and cattle.

5.17.2

atsy annaṃ paśyasi priyam \
atty annaṃ paśyati priyaṃ bhavaty asya brahmavarcasaṃ kule ya etam evam ātmānaṃ vaiśvānaram upāste \
pādau tv etāv ātmana iti hovāca \
pādau te vyamlāsyetāṃ yan māṃ nāgamiṣya iti \\517.2\

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 feet of the Ātman (Soul),’ said he. ‘Your feet would have withered away, if you had not come unto me.’
