An enlightened one like Mahavira, Gautama Buddha and Jesus Christ or Prophet Mohammed could say I had a kundalini awakening but would they ever say such a thing?
A true spiritual traveler never goes after kundalini awakening. For a seeker, welfare of entire mankind all the time was the only goal. State of enlightenment was bestowed as a grace by god.
On path of pure spirituality we had to demolish all desires and wishes in totality then how could desire for kundalini awakening subsist!
Apart from above enlightened ones even Sri Ramakrishna Paramhansa, his famous disciple Swami Vivekananda and Maharshi Ramana could effectively say, they had experienced kundalini awakening in totality.
Kundalini awakening is no small precept of spirituality. Activating kundalini to its fullest potential demands highest level of patience, persistence and perseverance that can ever be practiced by human beings! One has to become a Swami Vivekananda in real life.
What kundalini awakening means can be gauged from the fact that normal human beings used their brain 1 to 2% the balance always lying dormant! This includes even the brightest of scholars and entrepreneurs world over. It is said Albert Einstein had activated his brain about 4%.
Enlightened ones after kundalini awakening exercised their brain to full capacity 100%.
100% usage of brain means one need not indulge in written text anymore. Bookish knowledge becomes meaningless. One can draw entire wisdom contained in cosmos through Shruti jnana. An enlightened one after full kundalini awakening finally becomes knower of all, gains omniscience forever.
There was nothing like partial kundalini awakening. It is seriously advised that one must never indulge in partial kundalini awakening. Only when our goal of life is spiritual like Swami Vivekananda, we should indulge in kundalini awakening.
