Sri Kalki Purana by Sri Krishna Dvaipayana Vyasadeva

Among the upa-puranas or sub Puranas, the Kalki Purana is most sacred and widely respected. At the end of Kali -yuga, the Supreme Lord, Hari, will incarnate as Lord Kalki and kill all the mlecchas, yavanas, atheists, and Buddhists of the world that defy the Vedic authority. The pastimes of Lord Kalki are the subject matter of this literature, which is presented in story form. Exalted personalities can see everything, past, present and future. For this reason, there is no fault in narrating these future events as if they had already occurred. The Kalki Purana consists of thirty-five chapters.
