If a dam breaks loose can the flow of water be controlled? If not then kundalini awakening also cannot be stopped midway. Prime reason why Lord Krishna in Bhagavad Gita advocates the spiritual journey must be taken with caution. Once started, nothing could be reverted back.
Kundalini awakening results in opening of dormant lying portions of brain. Once these dormant lying portions of brain activated, they could not be reverted back to their original position. Prime reason why kundalini awakening let loose, quit midway can create havoc in life.
Kundalini shakti is the most potent of all energies made available to mankind by grace of god. It was designed to provide mankind with an upper edge over other lower forms of life. Kundalini shakti was meant to give impetus to mundane life so that human beings could realize their full potential, become a Mahavira, Gautama Buddha Jesus Christ or Prophet Mohammed.
At whatever level of spirituality we may be, we must stop all indulgence in contemplation (chintan) once and for all. We must stop thinking who we are, from where we came, what is our cosmic goal of life, our relationship with god, world of souls atmans… definition of karma, Dharma, difference between religion and spirituality and so on.
We must stop looking inward. We must also stop being spiritual or religious. We must never indulge in spiritual or religious discussion of any kind. We must also stop practice of celibacy (abstention from sexual indulgence) if any. Only then we can establish temporal control over kundalini awakening.
As spiritual journey is an inward journey, one cannot practically stop indulging in spirituality. Furthermore we are a spiritual being, a spirit manifesting human form. As a spirit, consciousness how could we stop our journey towards god. We as a soul atman are designed to merge with god. Whether we do it now in present life or postpone it for next manifestation is purely our prerogative.
