Reiki is a form of alternative therapy commonly referred to as energy healing. Developed in Japan in the early 20th century by Mikao Usui, Reiki is based on the idea that a universal life force energy flows through all living beings. Practitioners of Reiki use a technique called palm healing or hands-on healing through which a "universal energy" is said to be transferred from the practitioner's palms to the patient. This process aims to encourage physical or emotional healing by balancing the body's energy fields and removing blockages. 

 The practice of Reiki is believed to offer numerous benefits to the recipient. Physically, it is thought to promote relaxation, reduce pain, and accelerate the healing process. By alleviating stress and tension, Reiki can improve overall well-being and enhance the body's natural ability to heal itself. Many recipients report feeling a deep sense of calm and relaxation during and after a session, which can contribute to better sleep, reduced anxiety, and improved mental clarity. 

 Emotionally and spiritually, Reiki can provide a sense of peace and emotional balance. It is often used to support emotional healing by helping individuals process and release negative emotions and past traumas. The practice is also believed to enhance spiritual growth and self-awareness by connecting individuals to their inner selves and the universal energy around them. This holistic approach to healing emphasizes the interconnectedness of mind, body, and spirit, making Reiki a comprehensive therapy that supports overall health and well-being.
