The awakening of kundalini is possible only through yoga meditation, never otherwise. And why is kundalini awakening at all necessitated? People often asked can we awaken kundalini without indulging in yoga meditation. The answer is simple no.
Yoga is the precept, kundalini the path. Yoga derived from the root word yog means synthesis, effort to merge between two. The effort of a soul atman trying to merge with Brahman, God Almighty is called yoga. If people called yogic exercises (asanas) yoga they were totally ignorant.
To successfully indulge in yoga meditation first of all we have to demolition our ego in totality. This is a lengthy process but if we indulged in karma nishkama karma way of life, it becomes a reality. Furthermore to overpower five senses and mind we have to curtail desires and wishes in stages.
For a serious spiritual traveler who desires gaining absolute purity as a soul atman, desires and wishes simply did not matter. Indulging in jnana wisdom contained in Bhagavad Gita we can reduce our desires and wishes slowly step-by-step. Most important was indulging in nishkama karma yoga, offering fruits of karma performed to God Almighty all the time.
We can reduce desires and wishes if we can dissolve queries within. To remove darkness of ignorance jnana wisdom contained in Bhagavad Gita comes to our rescue. Following path of self enquiry, Neti (not this, not this) we can in stages establish control over five senses in totality. A logical approach to life is necessitated in the journey of spirituality.
Contemplation (chintan) is the only medium to indulge in Bhagavad Gita. Contents of Bhagavad Gita cannot be understood literally.
Be as commoners used our brain 1 to 2% the balance always lying dormant. By indulgence in kundalini awakening we can activate our brain to full 100%. For full awakening of kundalini shakti we have to practice absolute celibacy (stopping the flow of negative thoughts to our brain in totality is what absolute celibacy all about). On path of spirituality, practicing absolute celibacy is the most difficult task. Physical aspect of celibacy can be indulged easily (abstention from sexual indulgence) but stopping flow of negative thoughts to our brain takes time.
Practice of absolute celibacy is necessitated for full 12 years in continuation for full awakening of kundalini shakti. Anything less or in piecemeal would not do. Sage Vishwamitra, a highly accomplished Sage of his era on sighting a maiden woman taking bath in forlorn circumstances in deep dense jungles fell from grace. He had to repeat practice of absolute celibacy all over again.
Indulgence in spirituality, kundalini awakening is the job of a seeker possessing willpower of Swami Vivekananda. Anything less would not do.
