Kalki

Kalki is the avatar who has not yet come. At the end of the Kali Yuga — the current cosmic age, characterized by spiritual darkness, moral degradation, shortened lifespans, and the decline of dharma (Bhagavata Purana 12) — Vishnu will incarnate one final time as Kalki. He will appear riding a white horse (named Devadatta, “God-given”) (Kalki Purana), carrying a blazing sword (or comet-like weapon), and will destroy the forces of evil, punish the wicked, and restart the cosmic cycle with a new Satya Yuga (age of truth and righteousness) (Vishnu Purana 4.24).

The parallel to Revelation 19:11-16 is among the most striking in all of comparative religion: “Then I saw heaven opened, and behold, a white horse! The one sitting on it is called Faithful and True, and in righteousness he judges and makes war… From his mouth comes a sharp sword with which to strike down the nations.” Both traditions envision a future divine figure arriving on a white horse with a weapon, destroying evil, and inaugurating a new age of righteousness. Zoroastrianism contributes a third parallel: the Saoshyant, a future savior born of a virgin, who will raise the dead and defeat evil at the end of time (Frashokereti). Three independent traditions, three eschatological riders.

“At the end of the Kali age… a Brahmana named Kalki will arise, endowed with great power, intelligence, and prowess. He will destroy all the mlecchas and thieves, and will restore righteousness on earth.” (Vishnu Purana 4.24)
