People are not just physical entities. We have dense or gross physical bodies that we can normally perceive by sight and touch. We also have a bioplasmic body or energy body which is invisible and this directs the state of the physical body and our emotional self. Medicine treats only our physical body- Reiki heals us completely, our physical body and our emotional self. Thus Reiki heals the whole person. For example, when a person has a headache and comes to a Reiki healer, the healer will place his hands on the head points and give relief. The headache may have its source in the digestive area and if this is so the energy goes to this area as well as the head and heals the problem at the source.
If the pain is caused by stress then it removes the source of stress. In case of serious diseases the source is usually more than physical and these normally have their roots in emotional trauma. In spiritual despair or negative mental patterns or because of deep resistance to someone or something, Reiki is very helpful in healing all these from the roots.
Reiki raises the level of awareness, makes people more present to life, frees from delusion, stress and disease.
