Reiki is a Japanese technique for stress reduction and relaxation that also promotes healing. It is administered by "laying on hands" and utilizes the "life force energy" that flows through us. If one's "life force energy" is low, then we are more likely to get sick or feel stress, and if it is high, we are more capable of being happy and healthy.
Reiki heals by flowing through the affected parts of the energy field and charging them with positive energy. It raises the vibratory level of the energy field in and around the physical body where the negative thoughts and feelings are attached. This causes the negative energy to break apart and fall away. In so doing, Reiki clears, straightens and heals the energy pathways, thus allowing the life force to flow in a healthy and natural way.
Because Reiki is guided by the God-consciousness, it can never do harm. It always knows what a person needs and will adjust itself to create the effect that is appropriate for them. One never need worry about whether to have a Reiki session or not. It is always helpful!
