The mentor of Kalki Avatar in previous manifestation was Sri Ramakrishna Paramhansa. At that time even though Sri Ramakrishna Paramhansa insisted Swami Vivekananda did not agree to reach state of enlightenment, god realization, self realization followed by moksha salvation. That was the period between 1863 and 1902.
In present manifestation Swami Vivekananda would not only reach state of self realization, god realization but also manifest, don garb of Kalki Avatar. Yes, I am 100% correct that the avatar of Kalki would be Swami Vivekananda of yester years. Mounted with power of truth and only truth, mankind would witness a man-made fury totally unprecedented; ruthlessness not visible anywhere. This lone crusader Kalki Avatar would annihilate 5.5 million people under his charge.
The mentor of Lord Kalki Avatar would be God himself, Brahman in Hinduism. Mounted with power of Bhagavad Gita and Upanishads from a very early age this one-man army would finally succeed in re-establishing Dharma against all odds.
With a zero ego and possessing 100% faith in existence of God and world of souls’ atmans, this spiritual traveler of truth would finally succeed cleansing the society of its ills. He would convert the present Kali Yuga, rather usher the present Kali Yuga to Satyuga in no time.
Only the mentality of the people needs changing from material to spiritual. People remaining same their perception will change dramatically, drastically. About 95% people presently engrossed in material pursuits of life would change their go to spiritual journey.
If we can establish control over ego, demolish our ego in totality then Lord Krishna within, our soul atman residing in heart is all the time willing to help us. For one who has Lord Krishna by his side all the time, who can defeat one!
This happened with Arjuna! The entire army of Lord Krishna was with Kauravas yet Pandavas won the battle of Mahabharata. Why? It was only because Pandavas had Lord Krishna with them.
We must never forget on mother earth Lord Krishna represents power of god, the Almighty creator of entire cosmos Brahman himself. Lord Krishna allegorically stands for spirit, soul atman existing in human body. Every soul atman is God Almighty in miniscule form existing in us. Taking dictates from Lord Krishna from within means taking guidance of God himself. What more could a spiritual traveler desire from life?
