Bhagavad Gita 9.16

9.16 I am the Kratu; I am the Yajna; I am the offering (food) to the manes; I am the medicinal herbs and all the plants; I am the Mantra; I am also the Ghee or the melted butter; I am the fire; I am the oblation.

But it is I who am the ritual, I the sacrifice, the offering to the ancestors, the healing herb, the transcendental chant. I am the butter and the fire and the offering.
