In Hinduism, Kalki (Devanagari: कल्कि; also rendered by some as Kalkin and Kalaki) is the tenth and final Maha Avatara (great incarnation) of Vishnu who will come to end the present age of darkness and destruction known as Kali Yuga. The origins of the name probably lie in the Sanskrit word kalka which refers to dirt, filth, or foulness and hence denotes the destroyer of foulness, destroyer of confusion, destroyer of darkness, or annihilator of ignorance.
