Kalki is the final avatar or incarnation of the Hindu god Vishnu. Hindus believe that there are four stages of time. The stage of time we are in is called the Kali Yuga. In this stage of time, people are very bad. To make the world good, Kalki will come to Earth, and will destroy the bad things and kill the bad people. People will change then, and become good people. A new stage of time will begin, called the Satya Yuga or the first stage of life. He is deciding to only come when everybody on Earth is very cruel. Kalki will come after Buddha, his work is to punish people who not changed their behaviour even after Buddha taught the right way. Kalki will come within this millenium. He will take birth in India. According to Nostradamus prophecies Kalki is the Chyren who will be king of whole world.He establish rightness in earth after defeating the whole world. He will punish bad people without mercy. It is said that he will be ruthless to cruel people. Kalki will establish a Golden Age within the Kali Yuga, before becoming king of the world. It is said that Krishna told Arjuna on the battlefield that right after his death, there will be the beginning of the Kali Yuga. He says 5000 years after his death (6000 B.C.) will come a Golden Age within the Kali Yuga. After the Kali Yuga Golden Age which will last approximately 10,000 years, he will establish the real Satya Yuga by defeating Kali (Demon) who is also known as the prince of evil in vedic scriptures.
