The four-legged animals like the cows made a calf out of the bull who carries Lord Śiva and made a milking pot out of the forest. Thus they got fresh green grasses to eat. Ferocious animals like tigers transformed a lion into a calf, and thus they were able to get flesh for milk. The birds made a calf out of Garuḍa and took milk from the planet earth in the form of moving insects and nonmoving plants and grasses.
