Disconnection, when used in Scientology, is a term used to describe the severance of all ties between a Scientologist and a friend, colleague, or family member deemed to be antagonistic towards Scientology. The practice of disconnection is a form of shunning. Among Scientologists, disconnection is viewed as an important method of removing obstacles to one's spiritual growth.
