The battle of Mahabharata and subsequent sermon of Bhagavad Gita by Lord Krishna has a very subtle message hidden for entire mankind. This story relates to entire world, not only followers of Hinduism or those living in India.
Whenever society reaches a point of no return, to cleanse the society of its ills precipitates a mother of all wars, battle of Mahabharata. The battle of Mahabharata is no ordinary war, it is a war precipitated to re-establish Dharma (righteousness) against evil forces of adharma (lawlessness).
A battle of the magnitude of Mahabharata results in very heavy casualties. To assuage the hurt feelings of entire mankind in such times advents a messiah, savior… avatar in Hinduism! Loaded with power of Bhagavad Gita and even Upanishads (independent spiritual treatises) an avatar like Lord Krishna not only succeeds in re-establishing dharma but also starting Satyuga (the golden period).
The sermon of Bhagavad Gita by Lord Krishna in Mahabharata is the ultimate message to mankind. Indulging in spirituality detailed in Bhagavad Gita any human being world over belonging to any religion faith or belief can indulge in teachings of Bhagavad Gita to reach cosmic end of life, state of enlightenment followed by moksha salvation.
The purpose of human life on mother earth always remained reaching state of moksha salvation. This is accomplished following the teachings contained in Bhagavad Gita.
No other scripture on mother earth can lead mankind towards state of enlightenment, moksha salvation.
In present times of total strife, tribulation mankind awaits advent of Kalki Avatar, one who shall annihilate dark forces of Kali Yuga. Kalki Avatar a one-man army would possess powers almost equivalent of Lord Krishna. And the advent of Kalki Avatar would announce precipitation of world war 3, a man-made calamity.
Only a few more years to go before Kalki Avatar surfaces, reveals himself.
