These existences, resting upon the supreme Divinity that is above Prakriti and that is without any inclination for action, uphold the entire universe of mobiles and immobiles. This sacred edifice of nine doors is endued with all these existences. That which is high above them, viz., the Soul, dwells within it, pervading it all over. For this reason, it is called Purusha. The Soul is without decay and not subject to death. It has knowledge of what is manifest and what is unmanifest. It is again all-pervading, possessed of attributes, subtile, and the refuge of all existences and attributes. As a lamp discovers all objects great or small (irrespective of its own size), after the same manner the Soul dwells in all creatures as the principle of knowledge (regardless of the attributes or accidents of those creatures). Urging the ear to hear what it hears, it is the Soul that hears. Similarly, employing the eye, it is the Soul that sees. This body furnishes the means by which the Soul derives knowledge. The bodily organs are not the doers, but it is the Soul that is the doer of all acts. There is fire in wood, but it can never be seen by cutting open a piece of wood. After the same manner, the Soul dwells within the body, but it can never be seen by dissecting the body. The fire that dwells in wood may be seen by employing proper means, viz., rubbing the wood with another piece of wood.

After the same manner, the Soul which dwells within the body may be seen by employing proper means, viz., yoga. Water must exist in rivers. Rays of light are always attached to the sun. After the same manner, the Soul has a body. This connection does not cease because of the constant succession of bodies that the Soul has to enter. In a dream, the Soul, endued with the fivefold senses, leaves the body and roves over wide areas. After the same manner, when death ensues, the Soul (with the senses in their subtile forms) passes out of one body for entering another. The Soul is bound by its own former acts. Bound by its own acts done in one state of existence, it attains to another state. Indeed, it is led from one into another body by its own acts which are very powerful in respect of their consequences. How the owner of a human body, leaving off his body, enters another, and then again into another, how, indeed, the entire range of beings is the result of their respective acts (of past and present lives), I will presently tell you.'"
