 Then we have Vishnu, who is the Preserver and Protector of Creation. This force of preservation is one which keeps and maintains harmony in the cosmos. And then when things grow out of balance, Vishnu will incarnate himself into a form necessary to help bring harmony back to creation. As an example, Vishnu is said to have incarnated nine times in Earth's history with his last two incarnations being as Krishna and Buddha. With a tenth prophecy to come at the end of a major cosmic cycle called the Kali Yuga. This in principle is very similar to the idea of Christ returning at the end of time.
