Kamadhenu is a Sanskrit word; Kama means desire, wish and dhenu is milk cow.
In Vedic scriptures Kamadhenu, also known as Surabhi (the fragrant one) and Matrika (the one who sets an example), is a heavenly bovine-goddess described as the mother of all cows as well as cattle. She provides her owner anything he requests and is an unbelievable "cow of plenty".
Hindus belonging to all cultures and languages from all parts of the country believe in the worship of the cow. The Gomata or the cow is a sacred symbol.
In the pictures Kamadhenu is portrayed as a white cow. Her complexion is like the white clouds. She has the body of a bovine, a female head with breasts, a peacock’s tail and wings like a bird. In some other pictures she is portrayed as a white cow with her body containing various deities.
Every part of the cow’s body has a religious significance. Its teats symbolise the four Purusharthas and its four legs signify the four Vedas. Its face represent the sun, its horns represent the moon and gods, its legs the Himalayas, and its shoulders Agni (the god of fire).
In Hinduism all cows are respected as the worldly personification of the Kamadhenu. As such, temples are not dedicated to Kamadhenu and she is not worshipped independently as a goddess. However, she is honoured by the veneration of cows in general.
Kamadhenu is an integral part of the Indian culture. She is the sacred cow which grants all desires and wishes. This divine cow emerged from the ocean of milk when the gods (suras) churned the milky ocean. Hence, she is considered to be the offspring of the Devatas and the Asuras. She is believed to be living in swargalok (heaven). The Gods presented it to the seven sages and it came into the ownership of Sage Vasishta in course of time.
Kamadhenu, according to the Vedas, is a goddess manifesting as a divine cow. She could grant any wish for the true seeker like her daughter Nandini. For Sage Vasishta Kamadhenu provided all his needs for the sacrifices.
Kamadhenu was the daughter of Daksha, the God who created the world according to the Anushasana Parva.
In Vedic ritual ceremonies the religious significance of the cow is obvious in the use of butter, milk, and ghee. The belief is that Brahma ordained that she should supply milk and ghee to be used for sacrificial rituals.
