Reiki is a simple process. The recipient simply lies on the couch and relaxes. If they are unable to lie down the treatment can be done in a seated position, the main thing is that the recipient is as comfortable as possible. There is no need to remove any clothing as Reiki will pass through anything, even plaster casts.
The practitioner gently places their hands non-intrusively in a sequence of positions which cover the whole body. The whole person is treated rather than specific symptoms. Reiki heals by charging negatively affected parts of the energy field with positive energy. Energy fields in the body each have different vibratory levels and Reiki practitioners use their hands to affect and hopefully rebalance these vibrations in the negatively affected part of the body.
