Bhagavad Gita Chapter 13.17
avibhaktaḿ ca bhūteṣu
vibhaktam iva ca sthitam
bhūta-bhartṛ ca taj jñeyaḿ
grasiṣṇu prabhaviṣṇu ca
Translation
Although the Supersoul appears to be divided among all beings, 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.
