The Scientology handbook describes an “assist” as a process in which people heal themselves. The concept is to removing the reason for continuing the pain. The philosophy seemingly places blame on the injured person, claiming it to be their internal choice..

Travolta claims, “People were standing around watching as I did [the assist]. You could actually see him confronting the pain and after a while he looked up at me and said ‘I feel better’ so I said ‘Okay end of assist.’"
