When the Age of Kali has almost ended, the Supreme Personality of Godhead will incarnate. He will appear in the village Śambhala, in the home of the exalted brāhmaṇa Viṣṇuyaśā, and will take the name Kalki. He will mount His horse Devadatta and, taking His sword in hand, will roam about the earth killing millions of bandits in the guise of kings. Then the signs of the next Satya-yuga will begin to appear. When the moon, sun and the planet Bṛhaspati enter simultaneously into one constellation and conjoin in the lunar mansion Puṣyā, Satya-yuga will begin. In the order of Satya, Tretā, Dvāpara and Kali, the cycle of four ages rotates in the society of living entities in this universe.
