Definition of Self-Inquiry (Vichara)
by James Swartz
"If you think inquiry is closing your eyes and looking within, you are sadly mistaken. You cannot see your face with your eyes open or closed unless you have a mirror. To see yourself you need the mirror of Vedanta, a word-mirror that reveals your self. When you look into a mirror you do not see the mirror, you see yourself. Self-inquiry is Vedanta. It is a lifelong practice of inquiry into the world, the Jiva and the self. Inquiry negates Jiva and the world, leaving only the self."
