How Does Reiki Heal?

Rei = spiritual wisdom
Ki = life energy
We are alive because life energy (ki) is flowing through us.
Ki flows within the physical body through pathways called chakras/meridians/nadis. Ki is present in the organs and tissues of the body and can pass directly through them.
It also flows around us in a field of energy called the aura.
Everything within us is energy and everything around us is energy.
Ki nourishes the organs and cells of the body, supporting them and their vital functions. 
When the flow of healthy ki is disrupted, it decreases the function within one or more of the organs and tissues of the physical body. Therefore, it is the disruption in the flow of ki that is the main source of illness. 
Reiki raises the vibrational level in and around the physical body where there are blockages in the flow of ki.
Reiki clears, strengthens and heals the energy pathways allowing the healthy ki to flow in a healthy way.
