If you are having experiences of energy winding or rolling up your spine, creating involuntary spasms, and rippling in strange ways through your body, you are possibly one of thousands each year experiencing what is known as a kundalini rising or awakening. You may feel frightened or disoriented by this non-ordinary shift, but if you can relax with it and understand it as simply a dynamic of your own evolution it can become a treasured ally on your spiritual path.
When we understand that all of creation is formed as molecular structures, mostly space and energy manifest in a multitude of forms, it becomes easier to meet the empty/spaciousness and the enhanced vibrational energies that appear in our bodies, and face all the changes they invite.
There are many reasons people suddenly have these shifts and awakenings. Often anintense spiritual or energy practice will open the body to the heightened energy known as kundalini by the ancient founders of the yogic system. Sometimes an intense concentrated period may activate this sleeping power, even such innocent practices as biofeedback, meditation, prayer, love-making, or the charge projected by the touch of another person who has this awakened energy. In the thousand reports I have collected over the last 30 years many people write of spontaneous awakenings, sometimes in moments of great interior stress, or while using plant medicines or psychedelics, or while sitting in silence at retreats. So if you are feeling as if your energy field has jumped from 110 to 220 or even 2200 you are not alone, although unfortunately you live in a culture that is totally unprepared to understand the power and potential of this experience.
If your experience plunges you into fear and anxiety, if it explodes you into ecstasy, or if it hits the brain centers that produce imagery you will likely be afraid you are losing your mind, and if you meet up with the wrong therapeutic model others will support this interpretation. But some part of you will know this is real and it is meaningful, even while the mind freaks out about it. If you can just be curious and open instead of afraid and contracted this will help it calm down considerably. You need to nourish the witness within you, that which is simply aware.
