I have said repeatedly that the fundamental problem with the philosophy that the Force Wielders all seem to buy into is a sort of bizarre bipolar disorder. As long as you're up, your fine, but the moment you stumble slightly it's almost inevitable that you spiral quickly down into the Dark Side.

Gryphon's take in UF and Scribbler's in Terran Jedi seem far more reasonable (and healthy!) to me.
