It has no dogma, and there is nothing you must believe in order to learn and use Reiki. In fact, Reiki is not dependent on belief at all and will work whether you believe in it or not. Because Reiki comes from God, many people find that using Reiki puts them more in touch with the experience of their religion rather than having only an intellectual concept of it. Dr. Mikao Usui, the founder of the Reiki system of natural healing, recommended that one practice certain simple ethical ideals to promote peace and harmony, which are nearly universal across all cultures. We are alive because life force is flowing through us.
Life force flows within the physical body though pathways called chakras, meridians and nadis.
It also flows around us in a field of energy called the aura. Life force nourishes the organs and cells of the body, supporting them in their vital functions. When this flow of life force is disrupted, it causes diminished function in one or more of the organs and tissues of the physical body. The life force is responsive to thoughts and feelings. It becomes disrupted when we accept, either consciously or unconsciously, negative thoughts or feelings about ourselves.
