Kaushitaki Upanishad 4.3

4.3.1

sa hovāca bālākir ya evaiṣa āditye puruṣas tam evāham upāsa iti /

3. Then said Bālāki: ‘Him who is this person in the sun—him indeed I reverence.’

4.3.2

taṃ hovācājātaśatrur mā maitasmin saṃvādayiṣṭhāḥ /

To him then Ajātaśatru said: ‘Make me not to converse on him! As the Great, the White-robed, the Pre-eminent (atiṣṭhā), the Head of all beings—thus, verily, I reverence him.’

4.3.3

atiṣṭhāḥ sarveṣāṃ bhūtānāṃ mūrdheti vā aham etam upāsa iti /

4.3.4

sa yo haitam evam upāste 'tiṣṭhāḥ sarveṣāṃ bhūtānāṃ mūrdhā bhavati //3//

He then who reverences him thus, becomes pre-eminent, the head of all beings.
