One of the most popular of the processions over the Deepam Festival, is that of the Kamadhenu, the wish fulfilling cow, and the Kalpavriksha, the wish fulfilling tree. Both of which emphasis the wish fulfilling aspect of Arunachala.
The Kamadhenu is a divine cow-goddess described in mythology as the mother of all cows. She is the giver of plenty and provides the owner with whatever he desires.
Theories as to the origin of the Kamadhenu are two-fold. One scripture describes her as the daughter of the creator god Daksha, and another narrates that Kamadhenu emerged from the churning of the cosmic ocean.
The Kalpavriksha is a mythological divine tree said to fulfil all desires. Its mythology narrates that the wish-fulfilling tree also originates from the churning of the ocean of milk afterwhich the god Indra, returned with the tree to his paradise.
