"More direct evidence comes from a careful study of Large Group Awareness Training programs, variously known as Erhard Seminars Training (est), Lifespring, or simply the Forum. The basic procedure of these courses parallels the group training workshops … but the emphasis shifts from group effectiveness to personal development. By talking through life challenges, aspirations, fears, and the like with fellow participants and professional counselors/teachers, individuals hope to change how they view themselves, their family and friends, and their prospects for a fulfilling life."
