Energetic healing is just what it sounds like: the ability to cure something using your ki/psi powers. The techniques for this do not seem to be of any great difficulty, but they take great focus and concentration. To heal properly, one must not be distracted by any thoughts that are not based on the person he/she is healing, the ailment and condition of said person, and the performance of the healing technique he/she is using to heal it. This is perhaps one of the greatest ki/psi abilities due to how much it can help people despite its apparent simplicity. This ability can also be related to vitakinesis. A related term/ability would be Therapeutic Touch: the ability to heal by touch through psychic energy.
Energy Massage This technique is based on the element of water (not classified as hydrokinesis, though) and is quite simple, yet it will make your patient feel much relaxed after performing this technique. Have your patient lay face down and have him/her tell you where the best place to massage is. Massage that area in this simple motion: put both hands next to each other with the thumbs touching, squeeze the skin with both hands, and then let go of it, flattening both of your hands as well as letting your thumbs slide across the skin. While you are massaging, imagine a veil of blue (or white; whatever color that could be a "healing" color) energy surrounding your hands.
Note: This doesn't have to only be done on bare skin. It can be done through clothes, too.
