After advent of Kalki in full form he would instantly developed a dedicated following of above 2000 million people worldwide. Another 1000 million people would follow him though not blindly.
Such would be the efficacy of truth administered by Kalki avatar that the coming 200 years beyond 2025 will be period of golden rule, the awaited Satyuga. The annihilator of Kali Yuga (dark forces of nature) Kalki avatar would be one without a precedent except Lord Krishna.
Manifesting power of Bhagavad Gita and Upanishads (independent spiritual treatises), Kalki avatar would deliver the ultimate wisdom available to mankind in conceivable form. For the first time mankind of today would realize what Bhagavad Gita is all about and also merits of travelling spiritual path, reaching state of self realization, god realization.
Arrival of Kalki avatar does not mean people worldwide following Hinduism. Yes Bhagavad Gita forms part of Hinduism yet it was a universal document. Anyone world over even while following ones religion can ceremoniously indulge in teachings of Bhagavad Gita to reach state of self realization, god realization. To follow Bhagavad Gita one need not convert to Hinduism ever.
The power of Kalki manifests in power of truth and only truth. Spirituality truth signifies God. In the power of truth exists, God. We can say truth is God personified. This is also evidenced in the glowing faces of Westerners who were truthful not only from outside but also inside.
People in India though harboring malicious intentions always seemed truthful externally. What use practicing external truthfulness when the place of worship, our heart is sullied with untruth! Do we not realize that God Almighty existed in miniscule form as our soul atman residing in heart!
As the present journey of life belongs to our soul atman within, our remaining untruthful is the primary cause of all woes and worries in this world. Just by becoming 100% truthful we can change not only our present but also manifest future.
Masses in galore would follow Kalki avatar primarily because of his truthfulness, something potentially advocated by teachings of Lord Krishna in Bhagavad Gita.

Respected Shri Vijayji,
thank you very much for your sharing your knowledge on your blog.
Few years ago I had done intensive meditation for weeks in seclusion. I focused on breathing. After 2- 3 weeks of meditation my body began to shake on it’s own. That time I did not know that Kundlini was getting purified. In the beginning I resisted the shaking of the body. Later I allowed it. After long periods of total focus I turned my gaze on heart and breath. Very soon all of a sudden I saw a tunnel opening and I knew I will have to enter it. Some fear did not allow me to enter into the tunnel. I opened my eyes and did not try to meditate intensively again.
I have continued my meditation few hours every day. I take time to reflect, contemplate on knowing that I am not the body, mind, feelings, emotions. I have no desires nor fears. I know, I will not take birth again. Isn’t that not enough?
Please comment.
