Varaha- Hindu myth: a boar headed avatar of Vishnu that dived into the ocean to save the earth after a demon had put it on the bottom of the ocean. He lifted the earth up on his tusks and back into the sky.
Kalki translates to 'Eternity,' 'White Horse,' or 'Destroyer of Filth' and is the final incarnation of Vishnu, foretold to appear at the end of Kali Yuga, our current epoch. Puranas foretell that he will be atop a white horse with a drawn blazing sword. He is the harbinger of end time in Hindu eschatology, after which he will usher in Satya Yuga.
