If I am not the body and not the mind, then who am I? This question has been haunting humanity since the beginning of time. It is what Ramana Maharshi called self-inquiry which questions the nature of reality. Identified with the limited mind-body complex, we struggle in the world to survive, not knowing that we are not this limited entity but the pure awareness that transcends duality. We are the non-dual awareness that we seek. Every move and every thought is in the direction of this pure awareness (sat-chit-ananda) which is our true nature.
