L. Ron Hubbard was an esoteric scientist, who explains about Scientology, they defamed his book that was never published but is here on the internet called "excaliburg" defaming him with the fact that his writings drove people crazy. He went on a trip to Tibet where they performed interesting esoteric practices that spiritually cleanse your body. He talks about the fact that people with souls are called thetans and can break the cycle of reincarnation, that all souls are good and those that are "bad" are thus caused by traumas and society, both from this life and past lives. He created a device called e-meter, measure, which seeks to identify and eliminate "engrams", which according to Hubbard, are memories of traumatic experiences that affect people's behavior and mental health. The E-meter is used to help detect these engrams, based on the belief that emotional and mental responses to specific questions are reflected in changes in the conductivity of the skin, causing movements in the E-meter needle.
