Wikipedia: From Vasuki to Dhanvantari

Vasuki

I remembered Bhima almost died from the hand of Duryodhana. Duryodhana threw him in the river and he ended up going to another world at the bottom of the river. There is met King Vasuki and Vasuki gave him a special gift. He is a king of the nagas.

Ocean of Milk

A big story Vasuki took part of was the churning of the ocean of milk. I wanted to know what the ocean of milk was. It is the 5th from the center of the 7 oceans. It surrounds the country of Krauncha. Some gods stirred up the ocean to release the nectar of immortal life, Amrita. 

Amrita

Amrit in Sanskrit means immortality. Amrita is usually a nectar in many religions. It sometimes is said to flow on statues of Hindu gods. The gods had to get the nectar to keep their immortality. Amrit was the last of the 14 treasure jewels of Hinduism that was contained in a pot borne by Dhanvantari.

Dhanvantari

He is an avatar of Vishnu. He is the physician of the gods. People pray to him to bring good health. He supposedly emerged from the Ocean of Milk.
