After indulging in kundalini awakening for a while if something goes wrong and we decide to quit the journey of kundalini awakening altogether then we can definitely shut down any further progress on path of pure spirituality. But whatever we have gained until now could not be reverted back ever. At whatever level our awakened kundalini exists, it will continue to do so.
All gains on path of spirituality, kundalini awakening were permanent always and ever. Chances of reverting back to normal routines of life were nil. For this very reason one must start journey of spirituality, kundalini awakening with caution.
Kundalini awakening was like an awakened serpent that could not be put to sleep again. We have to bear with it all along. The simple reason for this is, intermittent partial kundalini awakening results in opening of dormant lying portions of our brain. All activations in the brain always were permanent, could never be reverted back. Just like a bud that blooms into a flower could not become a bud again.
Forcibly if we stop a bud blooming into a flower, it will just wither and die. The same happens with human beings. Partial kundalini awakening can sometimes cause havoc in life of human beings. I have seen people going awry, becoming patients of severe depression.
The awakening of kundalini is directly linked to spiritual journey, an inner journey taken by human beings towards the spirit, soul atman existing in heart. If our goal of life is not spiritual and we do not desire reaching god in our lifetime then we must never indulge in kundalini awakening whatsoever. There was no other purpose of kundalini awakening!
Kundalini awakening properly indulged leads mankind to reaching state of enlightenment, becoming a Mahavira, Gautama Buddha Jesus Christ or Prophet Mohammed at the end of journey.
