Kalki is the prophesied tenth and final avatar of the Hindu god Vishnu, who is believed to appear at the end of the current age, the Kali Yuga (Age of Darkness), to restore righteousness (dharma) and bring about a new era of truth and justice.

ancient scriptures like the Puranas, Kalki is depicted as a mighty warrior, often riding a white horse and wielding a sword that shines like a comet. His arrival symbolizes the end of the current cycle of time, where evil has reached its peak, and the beginning of a new cycle of truth and virtue. Kalki's purpose is to eliminate corruption, ignorance, and injustice, re-establishing moral order in the world.
