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.

“O My Lord, Supreme God of the brahmanas, You are the well-wisher of the cows and the brähmanas. Dear Lord Krishna, You are the well-wisher of the entire human society and world and the beloved of the cows, who You love so much. Please accept my humble obeisances.” (Vishnu Purana 1.19.65)
