At this, the king addressed the earth and asked her to quickly minister to the needs of all beings, whether moving or fixed. The land promised to obey the behests of the king. Then the king, after making Svâyambhuva Manu as the calf, milked the earth in the form of the cow with his own hands. The earth then produced the different kinds of grain, which support mankind; after which the sages, using the moon as the calf and Bṛihaspati as the milk-man, milked the (earth) cow and extracted the milk of virtue in the pot of the Vedas. Then the Devâs, after making the God Indra the calf and the God Mitra as the milkman, milked the (earth) cow. They drew out the milk of elixir-vitæ in the pot of gold. The Piṭṛis also milked the same thing in the pot of silver.—14-18.—14-18.
