Krishna an avatar of his era (God manifest in human form) returns only at opportune moment when life practically loses its meaning on mother earth. With a complete decay in moral and ethical values society slowly reaches a point of no return. In such circumstances to re-establish Dharma (righteousness) advent of an avatar is mandated by God.
Earlier Krishna came during Dwapar Yuga when totally inhospitable conditions of total strife existed. In present times to annihilate dark forces of nature mankind awaits advent of Kalki Avatar, the messiah savior of present era, modern times.
Kalki avatar would manifest powers almost equaling that of Krishna.
As detailed in Bhagavad Gita life comes full circle on mother earth every 3500 to 5000 years. It is at this time appears a messiah, savior to save mankind from total destruction.
Lord Krishna represents soul atman existing in human body. When it activates, its colossal power almost starts a new journey of life on mother earth. With coming of Kalki Avatar mankind would witness start of Satyuga (the awaited golden period).
In a short while from now between 2022 and 2025 mankind would witness advent of Kalki Avatar. A mother of all wars is in making. The society has almost reached its lowest ebb. The moment it peaks, world war 3 would start. We still have 4~5 years more to go before start of world war 3.
Who wants a world war? Perhaps none! But to re-establish Dharma (righteousness) against evil forces of adharma (lawlessness), a battle of Mahabharata is the only available solution. It is at such times a Krishna surfaces.
Allegorically human beings world over are becoming materialistic day by day. Most passionate earthly relationships have almost vanished, only superficial ties exist. Inside human beings a battle of Mahabharata is ensuing between positive and negative forces of nature. Every single moment thousands of positive and negative thoughts clashed with each other.
The result, both Amrita (elixir of life) and Vish (poison) is produced. Seekers, travelers of spiritual path succeed guiding Amrita towards full awakening of kundalini shakti but what of commoners, masses! The Vish (poison) retained in the body of all is the cause all calamity. Day by day human beings are losing values, at times behaving worse than animals.
In the circumstances it is the might of Kalki Avatar that would set things right.
As a human being the best we could do in present circumstances is invoking positive thoughts most of time. Only those with a sunny disposition and godly thinking would fare well in coming times. Those deeply involved in vice and unethical and immoral practices would be outright wiped off the surface of Earth. In coming world war 3 almost 20% population of world would be wiped out, almost 1200 million people.
It is in such times words of wisdom from an avatar of the stature of Krishna is required.
