At this time the Handbook to Higher Consciousness was selling about fifty thousand copies a year, and his workshops attracted students from all over the country. In 1974 Keyes banned drug use from the Center. He wrote more books and they began to sell rapidly. His staff, which included Shakti Gawain, Tolly Burkan, and Summer Raven, worked on the workshops and activities such as writing songs to go along with them. Cornucopia in Kentucky Having outgrown the Berkeley center, in mid-1977 the organization bought a 150-acre (607,000 m2) property in St. Mary, Kentucky that had been a Catholic seminary. The organization moved to the new property, which it renamed "Cornucopia." Soon after the move, conflict developed between Keyes and the organization's head administrator and training director, Carole Thompson. Keyes had hired her in Berkeley, but, he said, he later thought she was influencing the staff in unhelpful directions. According to Keyes, she refused to allocate staff to him for the workshops he led, and he felt she was trying to edge him out of teaching and into the financial side of the operation. Similar "power moves" occurred during the Berkeley years, inevitable byproducts of a growing organization. Ken dealt openly with these issues using methods that he taught to keep the organization and vision on track. The week-long retreats during this time without Ken included such things as eating vegetarian meals, doing "karma yoga" work (chores) around the grounds, daily workshops based on The Handbook to Higher Consciousness principles, and watching the Franco Zeffirelli film, Brother Sun, Sister Moon, about the life of St. Francis of Assisi. These practices had been a part of daily life at the Berkeley house and all residents participated. The goals were to expose participants to teamwork and health consciousness while supporting day-to-day organizational functions. One of the more interesting exercises, also practiced in Berkeley, occurred when participants randomly selected a partner (done by forming two circles, one inside the other, with the outer circle moving clockwise, and until the leader said "stop" forcing people to choose diametrically opposite partners). A four-foot piece of cord was given to each "couple," and each was told to tie one end to his or her wrist. Thus, partners were literally tied together for the next 24 hours. It was a complication to use the bathroom, especially if one's partner was of the opposite sex. The purpose of the
