Lord Dhanvantari is known as the father of Ayurveda, since he was the first divine incarnation to impart its wisdom amongst humans. He first appeared during the great churning of the cosmic ocean of milk (Samudra manthan) to deliver amrit (ambrosia, or the divine nectar of immortality) to the demigods. The churning of the ocean of milk is a famous episode in the Puranas that represents the spiritual endeavor of a person to achieve Self-realization through concentration of mind, withdrawal of the senses, control of all desires, austerities and asceticism.
