Just as a mother produces various children, both male and female, the womb of mother earth produces all kinds of living entities in various shapes. Thus it is possible for mother earth to take on innumerable shapes. At this time, in order to avoid the wrath of King Prthu, she took the shape of a cow. Since a cow is never to be killed, mother earth thought it wise to take the shape of a cow in order to avoid King Prthus arrows. King Prthu, however, could understand this fact, and therefore he did not stop chasing the cow-shaped earth.
