Kalki Avatar, the name itself spelling nemesis of Demon Kali would surface only at the opportune moment. Kalki Avatar presently exists in India but aloof from society. And why is it so?
If Mahavira, Gautama Buddha even Jesus Christ or Prophet Mohammed manifest in present times, not even a single soul on mother earth would be able to recognize them. The reason is apparent; human beings used their brain 1 to 2%, the balance always lying dormant.
Comparatively enlightened ones used their brain 100%. With limited spiritual knowledge, one could never realize the might of an enlightened one. Physically Kalki Avatar would be one amongst us, but internally one would be a truthful soul, a liberated soul full of truth and only truth.
An avatar in India as per Hinduism advents only at the opportune moment when strife, tribulation peaks, never before! The only purpose of advent of an avatar is re-establishing Dharma (righteousness). Rest everything can be taken care by an enlightened one like Sri Ramakrishna Paramhansa and Maharshi Ramana.
Mahavira, Gautama Buddha even Jesus Christ and Prophet Mohammed came long time back yet even in present times the whole community, society is bonded together by the principles of spirituality dictated by these four spiritual stalwarts.
Apart from wisdom of enlightened ones, teachings of Lord Krishna in Bhagavad Gita form the core of entire spirituality. In absence of wisdom contained in Bhagavad Gita none in this world can reach stage of enlightenment followed by moksha salvation. Even the four spiritual stalwarts named above followed teachings of Bhagavad Gita in toto.
Furthermore, the end of goal Kali Yuga is still a distance away, maybe 5 to 7 years. Between 2022 and 2025 I expect advent of Kalki Avatar, rule a sight to behold.
