Vishnupurana 2.7.41

2.7.41

tad brahma tat paraṃ dhāma sadasatparamaṃ padam
yasya sarvam abhedena jagad etac carācaram //

This Vishńu is the supreme spirit (Brahma), from whence all this world proceeds, who is the world, by whom the world subsists, and in whom it will be resolved. That spirit (or Brahma) is the supreme state of Vishńu, which is the essence of all that is visible or invisible; with which all that is, is identical; and whence all animate and inanimate existence is derived. He is primary nature: he, in a perceptible form, is the world: and in him all finally melts; through him all things endure. He is the performer of the rites of devotion: he is the rite: he is the fruit which it bestows: he is the implements by which it is performed. There is nothing besides the illimitable Hari.
