Kalki Avatar, the last of the Maha Avatars of Vishnu, is yet to appear towards the end of the Kali Yuga or the Dark Age. The Kali Yuga is the Iron Age. So Kalki will be the Avatar or the Incarnation in the age of machines.

He is described in the Vishudharmottara Purana as a robust young man, riding on his white horse, Devadutta and with a shiny sword raised in his hand. While some sketch him as being four-armed, most of the records focuss on him as a two-armed. The scriptures picturize Kalki`s emergence "as a blazing Light" when He descends from heaven. This hailing of the Avatar resembles the Second Coming of Jesus.

The portraiture of Kalki is imbued with symbolic overtones. Kalki would ride on the horse of purity and might, and ward off and destroy the prevalent evil with his lashing sword of Dharma or righteousness. Therefore his name is endowed with deeper meaning. The name Kalki, literally communicates the meaning, "Annhilator of Ignorance". Vishnu Purana affirms the resurrection of Dharma that Kalki will usher in: " …And the minds of those who live at the end of the Kali age, shall be awakened, and shall be as pellucid as crystal.

The men who are thus changed by virtue of that peculiar time,
Shall be as the seeds of human beings,
And shall give birth to a race who shall follow the laws of the Krita Age, the Age of Purity."

The epic, Mahabharata specifically depicts the descent of Vishnu as the Kalki Avatar. The pious sage, Markendaya, illuminated Yudhisthir, the first of the Pandavas, on this precious knowledge. Markendaya informed that in a certain village called Shambala, Kalki would evolve. He will be born as a son to a virtuous Brahmin couple called Vishnuyasha and Sumati, on a bright fortnight of the lunar month of Vaishakha [beginning on approximately 21 April and ending on approximately 21 May on the solar calendar], on the 12th lunar tithi or occasion of (Dvadashi). The Brahman boy will be endowed with the gifts of intelligence, strength and valor. He will assemble other Brahmins into a formidable army to squash evil totally.

He will be identified by two of the Nine Immortals or Chiranjeevin currently residing on the planet. They are characters from the Mahabharata, Parashurama and Ashwatthama. Parashurama is the sixth Avatar of Vishnu, who replanted the flag of Dharma, by wiping off the tyrannical Kshatriya clan or warrior class from the face of the earth. Ashwathama , the son of the Guru or teacher of martial arts of the Pandavas, Dronacharya. Parashurama will appear to be the spiritual guide of Kalki, by educating him to undergo penance. Parashurama himself meditated with utmost devotion for 1000years. Lord Shiva then blessed him with a divine weapon for cleansing vice, as a reward of such penance. He would help Kalki to march forward, following the same path, achieve the Ratna Maru sword and the heavenly parrot, Shuka from Shiva and accomplish his task.

He will marry Padma, the Avatar of Vishnu`s consort, Devi Lakshmi and have two children, sons Jaya and Vijaya . Kalki will also perform the grand Ashwamedha Sacriifice to abolish all vitiated kings and false prophets, before embarking on the mighty assignment of the final obliteration of evil and misery in the Kali Yuga. Kalki, as it has been mentioned will usher in the Krita Age of purity and excellence.After the completion of his work, the human shape of Kalki, will expose itselfin the four-armed cast of MahaVishnu and return to his celestial abode of Vaikunth.

Kalki will that redemptive force,that will purge Creation of the disgraceful burden of sins.
