Śaṅkarācārya's commentary

It is undivided in the different bodies, It is one like the ākāśa. Still, it appears to be different in all the different bodies, inasmuch as It manifests Itself only in the bodies. The Knowable supports beings during sthiti, the period of sustenance of the Universe; and It devours them at pralaya, i.e., at the time of dissolution. It generates them at the time of utpatti, the origin of the Universe, just as a rope gives rise to an illusory snake.
