How Kalki and Maitreya relate to other world Religions/Religious Relations
There are some groups within society who believe that Kalki Avatar and Maitreya are simply names for one figure known as "The Teacher." These groups claim that "The Teacher" for Christians is Christ, for Jews the Messiah, and for Moslems the Imam Mahdi or Messiah.
"The Teacher" is believed to be the Head of the Spiritual Hierarchy of Masters. The followers of "The Teacher" believe that he has love for people of any religion or of no religion at all.
There are two websites that discuss the relationship between Jesus and Maitreya. Both sites emphasize that Jesus and the Christ figure are not the same. They believe the term Christ refers to "the name of a function in the Hierarchy of Masters of Wisdom." One essay, "Jesus of Nazareth and Maitreya the Christ" by Peter Liefhebber outlines the differences between the two. Another essay, titled "Maitreya and Jesus"does the same.
Virtually all religious texts provide information regarding a future presence of some kind:
Christianity The figure known as Kalki in Hindu mythology is related to figures and beliefs in other world religions. The image of Kalki on a white horse is similar to the Christian text of Revelation 19:11-16: Then I saw heaven opened, and there was a white horse! Its rider is called Faithful and True, and in his righteousness he judges and makes war. His eyes are like a flame of fire, and on his head are many diadems and he has a name inscribed that no one knows but himself. He is clothed in a robe dipped in blood and his name is called The Word of God. And the armies of heaven, wearing fine linen, white and pure, were following him on white horses. From his mouth comes a sharp sword with which to strike down the nations, and he will rule them with a rod of iron; he will tread the wine press of the fury of the wrath of God the Almighty. On his robe and on his thigh, he has a name inscribed, 'King of Kings, and Lord of Lord'
The following text from the website Kalki shares similar imagery in describing Kalki: Kalki is the final incarnation of Vishnu who will appear at the end of the eon, when corruption is beyond every measure of control, necessitating the end of the world. He will rise from the sea on a great white horse (some say the fire-breathing doomsday mare called Badavagini) with a sword in hand. He will destroy the impure world, killing everyone except those who seek refuge in him. Having thus dismantled the world, Vishnu will reassemble a new and pure world that will be inhabited by the believers and the faithful.
Islam In the Islamic tradition there is a prominent belief that the Hindu Kalki avatar has already come and gone from the earth in the form of their religious leader, Muhammed. This belief has recently caused an uproar surrounding a new book based on this belief.
The following is only one example used to support this idea: In the 'sacred' book of Hindus the father's name of 'kalki autar' is mentioned as 'Vishnu Bhagat' and his mother's name as 'somanib'. In Sanskrit, 'vishnu' stands for Allah (swt) and the literal meaning of 'bhagat' is slave. 'Vishnu Bhagat' therefore, in the Arabic language will mean Allah's slave (Abdullah). 'Somanib' in Sanskrit means peace and tranquilty which in arabic is denoted by the word 'Amina'. Whereas the last Messenger Muhammed's (saw) father and mother's names were Abdullah and Amina respectively. (Message Magazine: Oct 97: Pundit Verifies Messenger was Foretold)
Like Christianity and Islam, other religions such as Judaism, Buddhism, and Zoroastrianism await a savior, or some form of an apocalyptic leader who will restore the earth like Kalki.
Hindu and Buddhist Text:
"Oh son of Kunti, at the end of the millennium all material manifestations enter into My nature, and at the beginning of another millennium, by My potency, I create them again." -Bhagavad Gita, 9.7
"[His] reappearance will knit and bind together all men and women of goodwill throughout the world, irrespective of religion or nationality..." (The Tibetan Mahatma).
