Ramana Maharshi's words:
"Therefore, summarily rejecting all the above-mentioned physical adjuncts and their functions, saying “I am not this; no, nor am I this, nor this” — that which remains separate and alone by itself, that pure Awareness is what I am.
This Awareness is by its very nature Sat-Chit-Ananda (Existence-Consciousness-Bliss)."
