Reiki is a Japanese technique that is used to heal physical and mental trauma, and to support mental clarity and spiritual well-being. In Japanese, the word "rei" refers to a higher intelligence that permeates all living and nonliving entities and guides the inherent functioning of the universe. The word "ki"refers to the nonphysical energy that flows through everything that is alive, including plants, animals, and human beings—because of this, ki is also often called "life force energy," and is known as qi or chi from other lineages.
Reiki Practitioners understand that everyone has the ability to connect with their own healing energy and use it to strengthen energy in themselves and help others. It is believed that a person’s “ki” or energy should be strong and free flowing. When this is true a person’s body and mind is in a positive state of health.
The combination of these two words is what defines reiki as "spiritually guided life-force energy."
When the energy becomes weak or blocked it could lead to symptoms of physical or emotional imbalance.
Reiki is the life energy that flows through all living things.
It also works in conjunction with all other medical or therapeutic techniques to relieve side effects and promote recovery.
