Mbh 14.54.2a

"'Vasudeva said, "Know that the three qualities of Darkness and Passion and Goodness exist, depending on me as their refuge. So also, O regenerate one, know that the Rudras and the Vasus have sprung from me. In me are all creatures, and in all creatures do I exist; know this. Let no doubt arise in thy mind respecting this. So also, O regenerate one, know that all the tribes of the Daityas, all the Yakshas, Gandharvas, Rakshasas, Nagas, Apsaras, have sprung from me. Whatever has been called existent and non-existent, whatever is manifest and not-manifest, whatever is destructible and indestructible, all have me for their soul. Those fourfold courses of duty which, O ascetic, are known to attach to the (four) modes of life, and all the Vedic duties, have me for their soul. Whatever is non-existent, whatever is existent and non-existent, and whatever transcends that which is existent and non-existent,--all these which constitute the universe--are from me. There is nothing higher (or beyond) me who am the eternal god of gods.[170] O perpetuator of Bhrigu's race, know that all the Vedas beginning with (the original syllable) Om are identical with me. Know, O son of Bhrigu's race, that I am the sacrificial stake; I am the Soma (drunk in sacrifices); I am the Charu (cooked in sacrifices for being offered to the deities); I am the Homa (that is performed); I am those acts which sacrificers perform for gratifying the deities; I am even the pourer of the sacrificial libation: and I am the Havi or libation that is poured. I am the Adharyu. I am the Kalpaka; and I am the highly sanctified sacrificial Havi. It is me whom the Udgatri, in the great sacrifice, hymns by the sound of his songs. In all rites of expiation, O Brahmana, the utterers of auspicious Mantras and benedictions fraught with peace hymn my praises who am the artificer, O foremost of regenerate ones, of the universe.
