In Japanese, Reiki means ‘mysterious influence’ which relies on a spiritual energy that is hard to define. It was started 90 years ago by Mikao Usui as a result of Buddist training which involved meditation, fasting and prayer, that led to him practice healing by the use of universal life force energy. But despite the vague descriptions; it really does work. My guest, Guido Terzaghi, practices at a health centre in the University town of Cambridge. His website is: http://www.spiritual-energy-healing.co.uk/home which gives much information on oriental Reiki, its science, videos, and with information on related therapies. Reiki is commonly practiced in many countries of the world. This programme not only explores its spiritual and practical side, but compares it to other forms of complementary medicine and healing, discovering that there are some common factors, and seemingly all these techniques use the same fundamental system to heal the body and mind. What is it?
