We are alive because the "life force energy"; it flows through us. The "life force energy"; it flows within the physical body through pathways called chakras, meridians, and nadis. It also flows around us in an energy field called aura. The "life force energy"; it nourishes the organs and cells of the body and supports them in their vital functions.

Linking the energy fields allows the Reiki practitioner to use the universal healing field and help channel positive energy into the areas that the client needs. Since the "Life Force Energy"; It is guided by a Higher Intelligence, it goes where the body needs it most, not always where one would expect it to go. The Reiki practitioner is only one channel for this energy. The practitioner cannot control or guide him; therefore, they cannot misuse it.

When a Reiki practitioner places his hands over his client's clothed body, Reiki flows through the practitioner towards the client. This transfer can feel like any kind of sensation: heat, cold, vibration, tingling, unusual heaviness, or sometimes, no sensation. Reiki infuses the body with a concentrated amount of "Life Force Energy"; (known in other cultures as Qi, Mana, and Chu’lel) and helps restore energy balance on the physical, mental, emotional, and spiritual levels that may have decreased due to stress, accidents, or trauma. For example, emotional problems can provoke reactions in the body; physical conditions can influence psychological states and affect their relationships. Life-threatening illnesses create stress, not only in the person who is ill, but also in their spouse and children.
