To apply any description to the Supreme Soul is to limit and bind that which is limitless and boundless. All we can say is that the Absolute Reality is satyam, (Truth), jnanam (Consciousness) and anantam, (Infinite).

His essential nature is sat-chit-ananda: (Sat) Absolute Being – He encompasses everything because there is nothing outside of him; (Chit) Absolute Consciousness – He is the complete consciousness who has Absolute Knowledge; and (Ananda) Absolute Bliss – He is eternal joy and no suffering.
