Tom Cruise's Scientology superpowers, No. 1: Shattering the suppression from a 15-year-old - 2021-09-05
In 1950, a well known writer for the pulps, L. Ron Hubbard, announced that he had figured out the meaning of existence. In his book published that year, Dianetics, he revealed that the thing propelling all life was the compulsion to survive.
Anything standing in your way, he said, "suppressed" that survival. And some people were suppressive themselves. "Suppressive persons" or SPs were diabolical and meant harm to the young Dianetics movement, which later turned into Scientology.
One of the bedrock concepts of Scientology today, more than 70 years later, is that bad things happening in your life (like an illness, for example) are being caused by your connection to a Suppressive Person who means Scientology harm. Or, your connection to a "Potential Trouble Source," a person who may be in turn connected to an SP.
