English Translation - Swami Sivananda
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.


English Translation of Sanskrit Commentary By Sri Shankaracharya's
9.16 Aham, I; am the kratuh, a kind of Vedic sacrifice; I Myself am the yajnah, sacrifice as prescribed by the Smrtis; further, I am svadha, the food that is offered to the manes; I am ausadham-by which word is meant the food that is eaten by all creatures. Or, svadha means food in general of all creatures, and ausadha means medicine for curing diseases. I am the mantra with which offering is made to manes and gods. I Myself am the ajyam, oblations; and I am agnih, the fire-I Myself am the fire into which the oblation is poured. And I am the hutam, act of offering.
