Kundalini In-Location Burst
Conventional kundalini is a spinal system of psychic energy which has vortexes or chakras. It uses these vortexes as distribution hubs. Medically these are ganglion, but that is a view from the physical plane.
To create a physical body which has ganglion, there must be a subtle blueprint or prototype which nature’s uses as the framework for the form. What serves as that subtle basis is chakras and what nature produced is ganglion or nerve bunches for distribution of energy.
Initially raising kundalini causes realization of its passage through the spine into the brain. If however the yogi can raise kundalini on a daily basis that passage becomes cleared to such a degree that kundalini abandons its resting place which is the lowest of the spinal chakras, the base (muladhar).
When this happens the yogi experiences front kundalini and left/right side kundalini. When that is discovered and when that is practiced regularly, the yogi finds that there is cell-burst kundalini, where individual cells take the initiative to release their kundalini potential into themselves as contrasted to sending their energy for a sex climax experience or for a kundalini rise through the spine (sushumna).
If the yogi continues to practice, he may discover middle burst kundalini which could happen anywhere subtle energy accumulates. In this experience, kundalini burst here or there, wherever there is infused breath energy stirring. The energy accumulates in a certain part of the body. It hold the charge. Then it fires this in a small or large bliss energy explosion. It does not move up the spine into the brain. I remains where it is and does not honor the chakra system. These kundalini rises are zonal if anything.
