that's cool, but I don't think hubbard studied brain endorphin effects.Dianetics is based on both rhetoric and auditing to get the brain endorphin effects.
Getting the brain endorphin effects does not require rhetoric.
But if the PC "cognitions" are to likely be in agreement with Hubbard's pseudoscience then it was recommended that they go up both sides of "The Bridge". So, co-auditing was recommended.
@Riddick when you go on-and-on about rhetoric I partially agree with you and partially disagree with you.
