Dhanvantari

In Hindu mythology, Dhanvantari is
the physician of the gods and is credited as the founder of ayurveda, a traditional system of Indian medicine.
Dhanvantari is born when the gods
and demons (supernatural beings)
churn the Ocean of Milk to produce
the nectar of immortality. In the
course of their churning, many precious things are produced, including
the goddess Lakshmi, the wishing-cow
Kamadhenu, and the Kaustubha jewel.
As the churning reaches its climax,
Dhanvantari himself emerges from the
ocean bearing the pot of amrta, the
nectar of immortality that has been
the ultimate product of the whole
endeavor. See also Tortoise avatar.
