Vishnupurana 1.19.86

Glory to that Vishńu from whom this world is not distinct. May he, ever to be meditated upon as the beginning of the universe, have compassion upon me: may he, the supporter of all, in whom every thing is warped and woven, undecaying, imperishable, have compassion upon me. Glory, again and again, to that being to whom all returns, from whom all proceeds; who is all, and in whom all things are: to him whom I also am; for he is every where; and through whom all things are from me. I am all things: all things are in me, who am everlasting. I am undecayable, ever enduring, the receptacle of the spirit of the supreme. Brahma is my name; the supreme soul, that is before all things, that is after the end of all.
