If one purifies the mind with undeviated devotion and love one will perceive the all-pervading infinite chaitanya (consciousness) as an all-glowing sun within oneself. When one enters into such a state, one is able to see a luminous halo emanating from the soul center three inches deep from the middle of the eyebrows, right at the opening mouth of sushumna. This luminosity spreads to all centers in the sushumna and runs through the nervous system to encompass all body parts, illuminating the body with its glittering brilliance.
