Verily the dawn is the head of the horse which is fit for sacrifice, the sun its eye, the wind its breath, the mouth the Vaisvanara fire, the year the body of the sacrificial horse. Heaven is the back, the sky the belly, the earth the chest, the quarters the two sides, the intermediate quarters the ribs, the members the seasons, the joints the months and half-months, the feet days and nights, the bones the stars, the flesh the clouds. The half-digested food is the sand, the rivers the bowels, the liver and the lungs the mountains, the hairs the herbs and trees. As the sun rises, it is the forepart, as it sets, the hindpart of the horse. When the horse shakes itself, then it lightens; when it kicks, it thunders; when it makes water, it rains; voice is its voice.
