They have three places. At the heart is the daksināgni, in the belly is the gārhapatya, in the mouth is the āhavanīya. Ātman (Self) is the yajamāna (sacrificer); the mind is the Brahmā (the doer); greed and so on (anger, jealousy) are animals (of sacrifice); mental strength is the vow; contentment and the organs of intellect are the instruments of the yajña (sacrifice); the action organs are the sacrificial objects (comparable to the havis or the rice); the head or the skull is the utensil; the hair thereon is the darbha (the dried grass used in homa); the mouth is the inner altar, the head are the four cups, and the two rows of teeth are the sixteen cups (kapāla) (of the sacrifice).
