Lord Vishnu has presented himself with different avatars on this earth. Lord Vishnu is prominent as the Preserver of the universe. Vishnu's restoring, shielding and conserving powers have been apparent in the world in a sequence of ten mortal incarnations known as Avatars. The avatars appear in order to balance the effect of good and evil upon the earth. It is believed that nine avatars have already descended, three in non human form, one in hybrid form and five in human form. Of the ten universally recognized avatars, nine have already appeared whereas the tenth is yet to appear. These ten avatars are also known by the name of Dasha Avatar of Vishnu.

The second avatar, Kurma, was taken in the Satyuga (last age) to help the Devas and to obtain the amrut (nectar) of immortality which was also sought after by the Asuras (demons). He helped in creating the world by giving support of his back through this avatar.
