Avatara is a descent of God for the ascent of man.
An AVATARA (or Avatar) is an incarnate of God, who has taken form on Earth to vanquish evil that has engulfed the world in darkness. This incarnate will take the form of something that is familiar to mankind so as not to insight suspicion or distract from the MESSAGE he wishes to convey. For example, Hindu scriptures proclaim that God, in this case, Lord Vishnu, will descend on Earth ten times in order to rid the world of the evils that have befallen it. As such, we have already witnessed nine of them: Matsya (the fish), Kurma (the tortoise), Varaha (the boar), Narasimha (half-man/half-lion), Vamana (the dwarf), Parasurama (Rama with an ax; the first warrior-saint), Rama (prince of Ayodhya), Buddha (aka Balarama; elder brother of Krishna; known as the Sankarashana form), and Krishna (essential character in the Mahabharata; marked the beginning of the Kali Yuga (the Iron Age). The tenth, who will be known as Kalki (the Destroyer of Filth) will emerge at the end of the Kali Yuga, mounted on a white horse and wielding a blazing sword. (written by Neelam Wadhwani)
