"est and Large-Group Awareness Seminars: Arising out of the human potential movement in the 1960s were a number of workshops, seminars and training programs. The most famous human potential program was erhard seminars training known as est. est was an intensive 60-hour workshop designed to alter a person's life view. There are a number of est clones including Life Spring, Actualizations and Forum, which is a successor to est. All of these workshops have several features in common. Participants are verbally attacked. The idea is to break down emotional defenses in order to allow new beliefs and attitudes to take over. There is a significant cathartic element in that emotional release is generated by the est techniques."
