DASAVATARAS (Ten Incarnations of Vishnu) 1 Mat-sya Avatar (Fish Incarnation) To save the earth from a great flood, Lord Vishnu took the form of a giant fish and lifted the earth above the waters. Kurma Avatar (Turtle Incarnation) The angels came to know there was Amrit (nectar) under the Ocean of Milk. Lord Vishnu lives on the Ocean of Milk. If this ocean is churned, they would get Amrit. If they drink amrit, they wouldn't have death. They live forever. To churn the Ocean of Milk, they needed the help of demons.

To support the mountain from below, Vishnu took the form of a giant turtle. They got the moon while churning. It was taken by Siva. Goddess Lakshmi was born next. She was taken by Vishnu. In this way, moon and Lakshmi are siblings. Next came, a dreadful poison. It was swallowed by Siva. At last came the amrit. By a trick, the angels drank all the am...

The Descent of the Ganga to the Earth The Ganga was originally a river in the sky. It was called Akash Ganga. Now, let's see why and how the Ganga came to the earth. Once upon a time, there was a king called Sagara. He had 60,000 sons. One day they went to the forest hunting. They happened to make a sage angry by their arrogant behaviour. He turned them to ashes. They died because of a sage's anger. So their souls could not reach the heaven. Many hundreds of years later, a descendant of them decided to send his forefathers' souls to the heaven. His name was Bhageerath. He asked many wise men what he should do to be able to send his forefathers' souls to the heaven.

So he prayed to the Ganga to come to the earth and flow along the land where his forefathers' ashes lay. The Ganga accepted his prayer but she warned that if she descended to the earth directly...
