Yes Reiki can trigger an activation of kundalini energy or a release of pranic energy that helps to keep opening the body and consciousness and feels like kundalini only not as intense.So can sincere devotion and meditation. I have found this especially true in the more advanced levels of Reichi initiation. Reichi generally opens a specific energy pattern rather than kundalini but in someone who is ready for awakening it can spill over to the kundalini force at the base of the spine. Kundalini is the way the subtle energy body responds to the shifts in consciousness that comes with spiritual awakening. It moves up from the base of the spine and intensifies the energy field in the entire body. If you just relax into it and trust it and don't "work" with it to try to push it there does not need to be any problem, although it can bring a lot of unusual phenomena, as described on my website. Sometimes it brings up old emotional issues as it seems to be a clearing process for our conditioning and a way that stress is released from the body. Devotion and a stable spiritual practice can be very helpful in this process. It ultimately takes us into a life that is lived more directly in the moment, more with presence and inner peace.
