Therapies built around the concept of energies that pervade and surround the human body have been around for centuries and are a part of Indian, Japanese, and Chinese healing traditions. Development of scientific concepts and accurate instruments has led to a renewed interest in the study of subtle energies and their effect on human health. Pranic healing is a form of energy therapy that originated in India; the practitioners try to remove disease-causing negative energy and substitute it with positive energy. Qigong originated in China and it stresses meditation, relaxation, and mind-body exercises. Reiki in Japanese means the “Universal Life Force”. Reiki practitioners consider the Reiki energy to be guided by a divine power.
