I think the Pleiadians are talking about the first phase Carl.
During this first phase you begin clearing your own material… and then find yourself coming into contact with bigger flows of energy. And bigger blockages. The traumas, wounds, and energies from our family, our ancestors, and past lives are processed- or come up for clearing. This is a deeply physical, emotional, spiritual process. It results in a lot of physical and emotional pain, existential crisis when your belief systems suddenly shift after you have cleared a big ancestral pattern (for example), and a lot of the symptoms discussed
here of twitching, lack of control, changes in the body/mind/spirit and even near-death experiences.
The first phase of Kundalini awakening is a very difficult process. Even though you may flicker– or realize “higher” experiences of oneness, bliss, peace, and all of the wonderful things of being in flow and having the direct experience that you are in divine flow– these are temporary as you sludge through the layers and layers of un-awakened Self. It is also true that Kundalini may flow up the spine higher temporarily as you realize the possibilities of the second and third phases of Kundalini. When Kundalini courses temporarily with great force, we get a lot of symptoms (like a great wave crashing on a rock) in the midst of it, and then our Kundalini becomes less active or forceful and returns to the first, second, or third chakra processing. So we may realize a further state (such as the second phase of K rising) but then we go back to what we need to process in the first when the energy becomes less of a tsunami and more of a gentle flow.
