The workshop, run by the Scientology Community Centre, is to take place in Cork next month.
It refers to a Hubbard Dianetics Seminar which focuses on a “hidden part of the mind” which Scientologists believe stores all painful experiences. Dianetics has been widely dismissed by the medical profession.
Former Scientologist Peter Griffiths voiced fears that the religion is spreading to Cork.
“The Church of Scientology has been in Ireland for 30 years but it is poorly represented in Ireland, with only around 89 members. However, it is getting bigger and bolder, and it appears that Cork is next on its list,” he said.
