K. Gordon Neufeld spent ten years in the Unification
Church. After leaving, he completed an M. A. in creative writing and
wrote about his experience
with the Moonies. He details the benefits in "
Writing Down the Pain: A
Case Study of the Benefits of Writing for Cult Survivors". He
wrote several articles
about his cult experience, before completing a
book,
Heartbreak and Rage: Ten Years under Sun Myung Moon, a Cult Survivor's Memoir. The introduction has an excellent explanation of mind control that
discards the image of "mindless robots" and incorporates
instead the
very helpful concept of "mental roadblocks".
