Kamadhenu, the cow of prosperity emerged with Lakshmi out the sea as did Chintamani, a wish-fulfilling gem and a tree called Kalpataru that bore every flower and fruit desirable. Kamadhenu had enough milk to feed the world for all eternity. In her hand, Lakshmi also held the basket of bounty - the Akshaya Patra overflowing with grain and gold.

Kamadhenu is associated with Lakshmi as she is the goddess of affluence and abundance, representing the beautiful and bountiful aspect of nature. She gave birth to seven daughters, the sacred river-goddesses Ganga, Yamuna, Sindhu, Narmada, Godavari, Krishna and Kaveri who nourished the earth and supported life.

To realise her, one must respect the laws of life and appreciate the wonders of existence.
