This document discusses Ayurvedic and Yogic perspectives on the nature of self. It describes the self as having three parts - the visible self, invisible self, and soul. The invisible self is composed of the five pranas, five senses, five organs of action, mind, intellect, ego and soul. It is linked to the universal macrocosm through energy channels called nadis. When the link between the invisible and visible self disintegrates at death, the soul is liberated. The document aims to answer the question "Who am I?" by exploring the relationship between the individual self and the universal whole according to ancient Indian philosophy.
