With the advent of Kalki Avatar everything depicted wrongly in the scriptures of different religions of the world would be laid bare. So much so that fallacies practiced by the Vatican would be revealed to mankind, prime reason why Christianity terms Kalki avatar as Antichrist.
None in this world would be able to ever challenge the judicious rulings of Kalki avatar. As Kalki avatar possesses jnana wisdom of Bhagavad Gita and also Upanishads (independent spiritual treatises). In times to come there would not be a single person who could even reach the level of Kalki avatar in terms of spirituality.
For this very reason every single fallacy contained in Christianity or Islamic Dharma would be put to scrutiny before the entire mankind. With a simple logical approach the entire world community would understand the underlying truth; separating right from wrong, truth from false.
And thus would start a massive revolution in the religious world of both religions Christianity and Islamic Dharma. Until now people believed what religious pundits, Maulanas and the clergy stated but now their untruth stands exposed with advent of Kalki avatar. Such would be the fury of masses that temples of worship at many places would be totally ransacked, desecrated.
The result, people would realize the folly of pursuing religious practices and masses will look forward to indulgence in spirituality detailed in Bhagavad Gita and Upanishads under the able preceptorship of Kalki avatar.
