15.7 It is eva, verily amsah, a part, portion, limb, fragment-these are all synonymous; mama, of mine, of the supreme Self; [Here Ast. adds 'narayanasya, of Narayana':-Tr.] which, jiva-bhutah sanatanah, becoming the eternal individual soul, will known as the enjoyer and agent; jiva-loke, in the region of living beings, (i.e.) in the world-.
As the sun (reflected) in water is a part of the (actual) sun, and goes to the sun itself and does not return when the water, the cause of the reflection, is removed, so also even this part becomes similarly united with that very Self; or, as space enclosed in a pot etc., delimited by such adjuncts as the pot etc., being a part of Space does not return after being united with Space when the cause (of limitation), viz pot etc., is destroyed. This being so, it has been rightly stated, 'by reaching which they do not return.'
Objection: How can the partless supreme Self have any limb, fragment or part? If it has limbs, then there arises the contingency of Its becoming destroyed through the dismemberment of the limbs!
Reply: This fault does not arise, since Its fragment, which is delimited by an adjunct arising out of ignorance, is imagined to be a part, as it were. And this idea has been fully explained in the chapter (13) dealing with the 'field'.
How that individual soul, imagined as a part of Mine, enters into the world and leaves the body are being stated: Karsati, it draws to itself; indriyani, the (sense-) organs-ear etc.; manah-sasthani, which have the mind as their sixth; and prakrti-sthani, which abide in Nature, which are located in their respective spheres such as the orifice of the ear etc.
When (does it draw the organs)?
