When kundalini energy arises there can be bliss and chaos as the body adjusts to a new vibration.
To the extent you can relax and let go into the energy it is likely to feel better and be less troublesome, but the truth is the function of kundalini is to clear out all the old debris of your history, so any unfinished emotional or psychological issues are going to arise to be made conscious and resolved.
When an initial arising moves all the way through the body there can be great joy and ecstasy and an altered world view that makes you feel completely at one with the world. This is an experience that will pass in a few hours or a few days, and most people feel confused and sad when they return to the felt sense of the former self. This energy is not about becoming high and joyful and staying there. It is about transformation. Just as any reconstruction begins with a deconstruction, so does personal transformation.
The activation of kundalini is an invitation to awaken to your true nature, that which lies beneath the psychological self you have constructed since birth to fit in and cope with the life you were given. Each of us has a unique set of circumstances because our history varies, but whatever is held in the body/mind will be subject to this transformation process, until at some point consciousness is able to be known in its primal and original form, as the vast and empty spaciousness in which all is one potential.
We cannot make this happen because the “I” that would try to manage it is not able to go along on this journey. The I we believe ourselves to be is a collection of assumptions, beliefs, feelings, impressions, opinions and memories that are in continual movement (chances are you do not think now the way you did at age 5 or age 20, because more data is in the system an old patterns died). “I” is a verb, not a noun, not a concrete and immovable object. It is a sense that holds a collection. This is greatly challenged in an awakening process and so you feel unstable, uncertain, and sometimes afraid of how you are changing. You are entering into a mystery, where perceptions change, emotions can be erratic, and you often feel unfamiliar to yourself. But along with this can be great waves of love, blissful sensations, insights, and moments of stillness and peace. A few people may hear an inner voice that says something like “Peace be with you” or “This is all okay”. Just remember that all that arises passes on, and that the reason that most of what arises happens is so that you can see through it and realize — oh this too is not what I am.
Learn to be present in the moment where you are and not dwell on old patterns and memories. Learn to bring energy into the heart which will deepen the sense of appreciation and gratitude for the present moment. Learn to accept with equanimity what you were in the past with all its shadow and challenges and be curious instead of afraid about who you are becoming. Don’t let the mind jump to conclusions. Ask it to relax and just see what happens instead of projecting possible scenarios.
Consider moving more from intuition and from the heart rather than the old ways of decision making. Take care of your body and stay in alignment with your deepest truth and authenticity. These are the ways to support the process and eventually return into a lasting presence and inner peace.
