Kundalini awakening is important if our goal of life is spiritual. If we desired reaching end of cosmic life, liberation from cycle of birth and death forever then kundalini awakening is for us.
Kundalini awakening means energizing the coiled Serpentine energy lying dormant in base of spine. This cosmic energy, kundalini shakti is energized indulging in spiritual practices like contemplation, practice of absolute celibacy and also celibacy (Brahmacharya Vrata).
Contemplation is taking path of jnana yoga (absolute wisdom) through which we realized the hidden underlying meaning of sacred texts of different religions of world. To cut darkness of ignorance path of jnana yoga is necessitated. In present Kali Yuga, Dark Age we can never cut darkness of ignorance via path of bhakti yoga or karma yoga alone.
Unless we master delicate art of contemplation nothing worthwhile in field of spirituality or kundalini awakening can be achieved. Bookish knowledge meant little on path of spirituality. Literally one can never understand anything in Bhagavad Gita, one has to dive deeper into the bottomless pit of wisdom contained in Bhagavad Gita via path of contemplation.
Most human beings world over did not want to indulge in contemplation (chintan) whatsoever. I took a 40 days world tour in 1985 to assess the brain capacity of individuals in search of god. I came back empty-handed. None knew anything about spirituality as detailed in Bhagavad Gita.
It is a misnomer that kundalini can be awakening practicing celibacy (abstention from sexual indulgence) alone. The physical aspect of celibacy meant little, 90% celibacy is always practiced mentally. We have to stop in totality flow of negative thoughts to our brain. After a while flow of positive thoughts also stops and one finally reaches stage of Nirvikalpa samadhi (state of absolute nothingness, when not a single thought entered our brain uninvoked).
As our practice of contemplation, indulgence in jnana yoga proportional our spiritual achievements like kundalini awakening. Intermittent kundalini awakening resulted in activation of dormant lying portions of brain. As queries within us dissolved forever, we climbed higher and higher onto uncharted levels of consciousness.
Finally full kundalini awakening results in 100% activation of brain. One finally becomes knower of all, a self realized, god realized being.
Kundalini awakening was an automatic process if we indulged in spirituality via path of jnana yoga.
