"Young (1987:132) assigns est to 'a family in which Arica, Assertiveness Training, Actualizations, Gestalt Therapy and several other psychologically oriented groups belong.' These, as well as Lifespring, Relationships, Self-Transformations, the Church of the Movement for Inner Spiritual Awareness/Insight and others, are what Paul Heelas terms 'self-religions.' For an investigation and analysis of Exegesis, an est derivative, see Heelas (1987)."
