I had a kundalini awakening experience shortly after my first Reiki attunement, but I didn’t know that is what it was until afterward and I researched it. I had never even heard of kundalini prior to the experience. My Reiki teacher had no idea what was happening to me. I was on my own. The result of my experience has been favorable, but the experience itself was terrifying. Emotionally I was all over the map. I felt like I was going crazy. I experience induced chi flow, couldn’t sleep for weeks, had difficulty staying on earth, if you know what I mean.
But within a couple months, I had a major healing as a result of the awakening, and well, nothing about me has been the same since.
I often hear people speaking of wanting to awaken their kundalini as if it is a wonderful, gentle experience. Kundalini is not “friendly.” It may have fantastic effects, but it is indifferent to your blockages and will persist until it either breaks through them or takes your sanity trying. It is “fire energy”. Once a fire starts, you can’t contain it.
I suggest one ventures into it with a teacher or guide who knows what they are doing. If you have a blockage, that energy will pool in that chakra forcing whatever issues are in it to the surface very rapidly. If you are not equipped with healthy coping mechanisms and someone who can guide you through it, it can have some very negative and lasting effects.
