Kamadhenu, the sacred cow which grants all wishes and desires, is an integral part of Hindu mythology. This divine cow, which lives in swargalok (heaven), emerged from the ocean of milk (kshira-sagar) at the time of samudra-manthan (the great churning of the ocean by the gods (suras) and demons (asuras). It was presented to the seven sages by the Gods, and in course of time came into the possession of Sage Vasishta.
Kamadhenu - the sacred cow which grants all wishes and desires
Go, the cow, is a symbol of the Earth... If this 'all provider' for humans had not been protected from ancient times, it would have been extinct by now- knowing the greedy & selfish nature of us humans.
Kamadhenu (Sanskrit: कामधेनु [kaːməˈd̪ʱeːnʊ] Kāmadhenu), also known as Surabhi (सुरभि Surabhī), is a divine bovine-goddess described in Hindu mythology as the mother of all cows. She is a miraculous “cow of plenty” who provides her owner whatever he desires and is often portrayed as the mother of other cattle as well as the eleven Rudras. (via wikipedia)
