Kalki Purana

The Kalki Purana is a Vaishnavism-tradition Hindu text about the tenth avatar of Vishnu named Kalki. The text is a Vaishnavism tradition text, where Bramha and other gods approach Vishnu for protection from the evils of the Kali yuga. After listening to stories of persecution, Vishnu promises to be born as Kalki in the family of Sumati and Vishnuyasha, in a village called Shambhala. He studies the Vedas and other texts, then marries a princess named Padmavati of Simhala kingdom. Kalki and his army then fight various wars and destroy all those who had persecuted and driven Hindu dharma out of their land. After the annihilation of the evil and restoration of the good, Kalki returns to Shambhala. This marks the end of Kali yuga, and the start of the new cycle of existence, with Satya yuga (also called Krita yuga). Kalki then returns to heaven, according to Kalki Purana. The Buddhist texts also mention a king named Kalki from Shambhala who leads an army to destroy the persecutors of dhamma; then after the victory of good over evil and attainment of religious freedoms, Kalki ushers in a new era. The Buddhist text is dated to about the 10th-century.
