This past time will come the Avatar Kalki or the Messiah of Jews and Christians, as prophesied by the great sage sukadeva Gosvami, who even mentions the name of his father, Visnu Yasa, who will be a wise scholar, a pure man, and the name of his village, Sambhala.
These words will be verified in time and place, one after another. Such is the authority of “Srimad-Bhagavatam”.
If the revealed scriptures take care to mention the name of an Avatar, it is so that one can detect false “incarnations divine”, invented from scratch by fanciful little intelligence. We cannot therefore consider someone to be the Avatar of the Lord, if the name of his father as well as his place of “birth” are nowhere mentioned in the authentic writings.
The bhagavata Purana, sacred book, for example predicts the advent of Avatar Kalki in just under four hundred thousand years, 400,000 years, and also gives his father's name as well than that of the village where it should appear. Therefore, no sane being can accept a shoddy Avatar, unacknowledged, or whose name is not mentioned in the authentic holy scriptures.
Avatar Kalki, the Divine Messiah, is that formidable figure who must annihilate the mass of atheistic beings born during the Kali Age. Today, while we are still only at the beginning of the Iron Age, many principles contrary to religion are already in force, and as this dark age progresses, many other pseudo-principles. religious will not fail to be introduced into society.
People will forget the true religious principles, enunciated by Lord Krishna, before the beginning of the kali age, which demand the surrender of oneself to one's Divine Anybody. Unfortunately, because of the age of kali, people without understanding will not surrender to God.
Even the majority of those who claim to observe the Vedic religion [of the Vedas, the original holy scriptures] oppose in fact to the principles of the vedas, the revealed writings. They invent a new form of religious principles every day and claim to justify themselves that any path also leads to liberation.
Atheists generally say that each of the hundreds and thousands of different opinions that circulate constitutes a valid principle of religion in the Vedas, and the influence of such philosophical views will only increase as the Kali Age progresses.
In the last phase of this age, Avatar Kalki, the Messiah, the dreaded manifestation of Kesava [one of the countless Names of Krishna], God, the Supreme Person, descends into this world to annihilate atheists. He will only save the devotees of the Lord.
The Kali Age, which began 5,000 years ago, which sees conflict, ignorance, irreligion and vice abound, where true virtue has all but disappeared, lasts for 432,000 years. In this dark age, immorality increases to such an extent that in the end the Supreme Lord appears in person, in the form of Avatar Kalki, to defeat demonic and atheist beings, save his devotees, and inaugurate a new age, the golden age.
