Pṛthu is the first king to be ritually consecrated under Vedic tradition. A sūtra in the Ṛgvēda calls the river Paruṣṇi a cow, the descendants of Manu a calf and the earth a bowl of milk. It is Pṛthu who milks the cow and fills the bowl to feed the calf. And, it is said that he had conjured agriculture and different grains in that very bowl. The earth thus nurtured by Pṛthu becomes Pṛthvi and he in turn becomes the first emperor of all earth.
