Kali Yuga

Kalki

He is prophesized to come as the end of Kaliyuga, at the hieght of peril and ego, when humanity is to be saved only by uprooting its evil through a final resolution. he is mentioned in the Vishnu, Matsya and Bhagva-ta Purana.
He rides a white horse with a fiery sword carrying us into
Satyuga. With rise in technology and the borderline devilish manifestations, this avatar is the symbol of a new beginning through a culmination.
