BG Chap 13 - The Paramātmā's svarūpa - Undivided
Although the Supersoul appears to be divided in all the separate living entities, He is undivided. He is one not divided up within all the jīvas who are separate entities. But He appears to be situated as if separate like each jīva. Also it is said in Vedic literature that one Viṣṇu is present everywhere by His omnipotence, just as the sun appears in many places to many persons. He is the maintainer, destroyer and creator of all things. It can also be said that as the cause, He is situated in all the moving and non-moving entities undivided, and as the effect or product, He is situated separately as each one. As Nārāyaṇa, He is the protector of the living beings during the duration of kalpa, the destroyer at the time of pralaya, and the creator at the time of creation.
