Śaṅkarācārya's commentary

An integral portion of Myself — of the Supreme Self, of Nārāyaṇa — is the eternal Jīva (individual soul) in saṃsāra, manifesting himself in every one as the doer and enjoyer. He is like the sun reflected in water; the reflected sun is but a portion of the real sun; and on the removal of water the reflected sun returns to the original sun and remains as that very sun. Or, it is like the ākāśa (space) in the jar, which is limited by the upādhi of the jar. This ākāśa of the jar is but a portion of the infinite ākāśa and becomes one with the latter on the destruction of the jar which is the cause of limitation; then it returns no more. Thus the statement "to which having gone none return" is quite explicable. To the objection — how can there be a portion of the Supreme Self who has no parts? — the answer is: it is only a portion limited by the upādhi set up by avidyā; it is a portion as it were, an imaginary portion.
