My gain in studying and applying Scientology is through fundamentals such as defining words and also the Tone Scale.* The reason why these two are so appealing is because they are universally true and useful.

*Tone Scale: A scale which shows the emotional tones of a person. These, ranged from the highest to the lowest, are, in part, serenity, enthusiasm (as we proceed downward), conservatism, boredom, antagonism, anger, covert hostility, fear, grief, apathy.
