I don't understand the quoted sentence from GP, what does that really mean? Also, you seem to think you don't choose your reality because it's "objective". Why do you believe that? From a relativistic point of view, wouldn't those occultists also think that their reality is the "real" one, and that you are choosing your reality out of sheer self-indulgence (or ignorance, or whatever)?
