Kalki is the prophesied tenth and final avatar of Lord Vishnu, destined to appear at the end of the Kali Yuga, when society is steeped in chaos and moral decay. His divine mission is to restore cosmic balance by vanquishing evil and reestablishing dharma, ushering in a new era of righteousness. Scriptures like the Kalki Purana describe him arriving on a radiant white horse, wielding a blazing sword to uplift humanity and cleanse the world of darkness. While the exact timing of his arrival remains unknown, many texts suggest he will emerge in India—possibly in Sambhal—and be born during the final phase of the Kali Yuga, guiding the transition into an age of truth and harmony.
