"A man deluded by the I-sense imagines, 'I am the doer'."
- Bhagavad Gita
"He who inhabits the organ of generation but is within it, whom the organ does not know, whose body is the organ, and who controls the organ from within, is the Internal Ruler, your own immortal self. He is never seen, but is the Witness; He is never heard, but is the Hearer; He is never thought, but is the Thinker; He is never known, but is the Knower. There is no other witness but Him, no other hearer but Him, no other thinker but Him, no other knower but Him. He is the Internal Ruler, your own immortal self. Everything else but Him is mortal. Thereupon Uddalaka, the son of Aruna, kept silent."
- Brihadarankaya Upanishad 3.7.23
