A Reiki healing is very simply performed. The practitioner places his or her hands upon the person to be healed with the intent for healing to occur, and then the energy begins flowing. Every person is different but typically Reiki gives a person a relaxed and restful peacefulness. After the session you could feel tired or invigorated but by the next day you should feel more energized. The more Reiki sessions you have the more powerful your reaction and sensations.
