And undivided, and in beings appearing divided,
And sustainer of beings, and That knowable is the devourer and originator.

Source: Milind S. Pandit

Undivided, yet appears as if divided in beings; He, the object of knowledge, is the creator, sustainer, and destroyer of (all) beings.

Source: The Bhagavad-Gita: The Sacred Song

Although the Supersoul appears to be divided, He is never divided. He is situated as one. Although He is the maintainer of every living entity, it is to be understood that He devours and develops all.
