Kaushitaki Upanishad 4.11

4.11.1

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

Bâlâki said: 'The person that is in the mirror, on him I meditate.'
Agâtasatru said to him: 'Do not challenge me on this. I meditate on him as the likeness. Whoso meditates on him thus, to him a son is born in his family who is his likeness, not one who is not his likeness.'

taṃ hovācājātaśatrur mā maitasmin saṃvādayiṣṭhāḥ /

pratirūpa iti vā aham etam upāsa iti /

4.11.4

sa yo haitam evam upāste pratirūpo haivāsya prajāyām ājāyate nāpratirūpaḥ //11//
