Reiki is a holistic Japanese technique for stress reduction, relaxation, and spiritual healing. Think of it like an energy massage for your mind and spirit. It will also help open up your intuitive and psychic senses because you will be in harmony with your personal energy. You may experience sensations in the body such as heat or tingling. Some people report seeing visualizations such as colors or pictures, opening their "clairs" or intuitive and psychic senses, etc. But overall, it's an energetic cleaning to remove blocks and get all your chakras in alignment.
