Kalki

Kalki is the tenth and final avatar of the god Vishnu in Hindu tradition, expected to appear at the very end of the Kali Yuga, the last and worst of the world-ages. Where Vishnu's earlier avatars (the fish, the boar, Rama, Krishna) came to preserve dharma within an age, Kalki comes to close the age itself.

The prophecy

The Vishnu Purana and Bhagavata Purana describe Kalki's coming in consistent terms. He is born in the village of Shambhala to a brahmin named Vishnuyasha. He rides a white horse named Devadatta and carries a blazing sword. As the kali yuga reaches its lowest point, he "will roam the earth, exterminating the thieves and robbers [the wicked] with the terrible speed of time," and by destroying those who have abandoned righteousness, he will usher in the renewal of the age, after which the world returns to a higher yuga.

The white horse

The image of a divine figure on a white horse bearing a sword places Kalki alongside a very old Indo-European end-of-the-age motif. The parallels with the rider of Revelation ("Faithful and True… riding a white horse") are often noted, though the traditions developed independently; both draw on a shared symbolic vocabulary of the horseman who ends an age by violence and begins the next by purification. Kalki is the Hindu instance of a widespread figure: the savior who arrives as a destroyer.

How he fits the cycle

Kalki is not a savior in the Christian sense, because his "salvation" is the closing of one turn of the wheel so the next can begin. After he restores dharma, the age of darkness ends and the cosmos proceeds toward its periodic dissolution in Pralaya and a fresh creation. His work is cyclical maintenance, not final redemption. In this he is closer to the Saoshyant than to a once-and-for-all redeemer, though he precedes the Iranian figure by sharing its deep structure: a final helper who sets the world right at the close.

Modern readings

In modern Hindu and esoteric writing, Kalki is sometimes read allegorically (as a future reformer or a force of knowledge) and sometimes literally (as a coming avatar expected in the current age). Either way, he remains the clearest statement in Hindu thought that the corrupt present is not the last word: the wheel turns, and at its bottom a sword appears.
