Usui Reiki is a form of alternative healing that originated in Japan in the early 20th century. It is based on the belief in a universal life force energy ("Rei" and "Ki" in Japanese) that flows through all living things. The practice involves a Reiki practitioner using specific hand positions, either on or near the body, to channel this energy to promote relaxation, balance, and well-being. Practitioners go through a process called attunement to connect with and transmit the healing energy. Usui Reiki is considered a holistic approach, addressing physical, emotional, and spiritual aspects of well-being, and it is often used as a complementary therapy alongside conventional medical treatments.
