The conscious introspective concentration of Self Enquiry ('Who am I?') kills all thoughts and destroys the dense darkness of nescience; it effaces all worry; it illuminates the intellect with the radiance of pure awareness; it wipes out all conceptual confusions; it fixes one in Siva-Self; it transforms a host of impending disasters into auspicious events; and lastly it destroys the ego-mind utterly with all its afflictions.
-- Ribhu Gita (Ch.32, v.24)
