The Kundalini Instrument in a human being consists of three Nadis: (Ida, Pingala, and Sushumna Nadis) and seven Chakras: Mooladhara Chakra, Swadisthana Chakra, Nabhi Chakra , Anahat Chakra, Vishuddhi Chakra, Agnya Chakra and Sahasrara Chakra.
Kundalini means "coiled energy" and refers to a power which lies in three and half coils in the sacrum bone which is situated at the lower end of vertebral column .A pulsation is sometimes seen at this level during Kundalini awakening. Like the Sushumna the Kundalini is normally in a potential state. When it is awakened it ascends to the top of the Sushumna. When Kundalini emerges at this point, Yoga (Union) is said to have taken place. This happening of Kundalini awakening and ultimate union with a higher consciousness is an inborn mechanism and is activated in a spontaneous and natural way without extreme efforts.
The human subtle system comprises of Three Nadis and Seven Chakras (plexuses).
- Left Sympathetic Nervous System is called the Ida Nadi and is connected to the right side and back of the brain. The two left and right channels cross at the Agnya Chakra level. This channel looks after our emotional life and our past. It is the channel, which creates our past. Whatever is present today becomes past tomorrow. The sub-conscious mind receives information from this channel. The subconscious mind has an age-old collective subconscious mind beyond it. Everything that was in the past since creation resides dormant in the collective subconscious. This collective subconscious has all that is dead in the evolutionary process collected and stored. Whatever that is dead or gone out of the subconscious mind goes out into the collective subconscious mind.
- Right Sympathetic Nervous System is called the Pingala Nadi, which crosses Ida Nadi at Agnya Chakra level. It is connected with the left side and the front of the brain. On the right hand side there is the supra-conscious mind, which creates our future. Whenever we think about our future it is recorded on the right hand side, and it also has a collective supra-conscious, which has got all that is dead, which happened due to over-ambitious, futuristic personalities, aggressive animals or plants. The above two left and right channels cross at the Agnya Chakra level.
- Parasympathetic Nervous System is called the Sushumna Nadi, through which the Kundalini passes to pierce through the 'Fontanelle bone area' (Little fountain or Brahmarandhra) to enter into the subtle energy of the all-pervading power. This is how the actualization of Self-Realization (Baptism) takes place. First the hands feel at the fontanelle bone area and on the fingertips the cool breeze of the Holy Ghost. The hands are steady, they do not shake, they look normal but the seeker feels the ripples of the cool breeze. For the first time he feels the existence of the all-pervading power.
