Bio-ching, a therapy technique that combines the insights of biorhythms with the wisdom of the I Ching, was developed by two eclectic therapists, Roderic and Amy Max Sorrell. Roderic Sorrell grew up in London. His mother was a devotee of Subud and he developed an early interest in occult and Eastern religions. He also studied with a group utilizing the teachings of George I. Gurdjieff. As an adult he became a therapist and began to integrate the various alternative spiritual teachings into his work. He found a compatible partner in Amy Max and through the 1980s and 1990s, they have traveled widely to sample a spectrum of alternative spiritualities. They studied martial arts, beginning with aikido, and were led to Tai Chi. They spent time in Hawaii studying Zen and many years in the San Francisco Bay Area studying Taoism. In the mid 1990s, they both took the Reiki training and emerged as Reiki masters.

Most recently they have moved to Truth or Consequences, New Mexico, and developed a retreat center which has become the major point of dissemination for their own synthesis called bio-ching. The I Ching is an ancient form of divination that derives information from the reading of one of 64 different hexagrams. Each hexagram is composed of six lines, each line being either broken or solid. Biorhythms are the three biological cycles as defined by William Fliess and Alfred Teltscher early in the twentieth century and popularized by George S. Thommen. The state of these cycles, each of a different length, can be calculated for each individual. Bio-ching relates each of the 512 possible combinations of the biorhythm chart on any given day with a particular hexagram reading. This is done by assigning two lines in each hexagram to one of the biorhythm cycles.

The Sorrells have established a retreat center in New Mexico for those who wish to participate in their therapy. Those who attend the ongoing events receive a personal bio-ching reading and are taught the art of journal-keeping so they can record their progress. Each day begins with Tai Chi and meditation , and each person receives some personal psychotherapy. Attendees are also introduced to Reiki healing, though the program is developed to individual needs and desires.

The Sorrells may be reached at 512 Marr, Truth or Consequences, NM 87901. They have a bio-ching Internet site at
