As a Healer, understand what exactly you are TOUCHING. We are physical beings having human experiences. The physical body is a vehicle to move and operate in this Earthly realm.
The human body is a combination of organs, blood, vessels, cells, your Spirit (which is your true self) and ENERGY. The space between the physical body and your spirit is an energy field called CHAKRA.
When you become aware of this energy field, you will begin to draw customers in need of healing. Their Spirit recognizes your power before you do; that's why one MUST protect their aura. You are a light and you draw ALL.
