Varaha Upanishad 2.37

2.37

ahiriva janayogaṃ sarvadā varjayedyaḥ kuṇapamiva sunārīṃ tyaktukāmo virāgī |
viṣamiva viṣayādīnmanyamāno durantā-ñjagati paramahaṃso vāsudevo'hameva ||

That Paramahamsa (ascetic) who, though living in the world, keeps aloof from human congregation as from serpent, who regards a beautiful woman as a (living)

corpse and the endless sensual objects as poison, and who has abandoned all passion and is indifferent towards all objects is no other than Vāsuḍeva, (viz.,) myself. This is saṭya (truth). This is nothing but truth. It is truth alone that is now said. I am Brahman, the truth. There is naught else but I.
