The mystic, the occultist, does not assert anything that a scholar cannot assert in his field. Let’s say that someone tells you a mathematical truth. If you haven’t studied mathematics you don’t have the necessary knowledge to verify this truth. No one will deny that to judge a mathematical truth the necessary capacities must be attained first. No authority can decide about such a truth, only the individual who has experienced it can judge. And only someone who has experienced an esoteric truth can judge it.
Our contemporaries, however, demand that the occultist prove what he says to the satisfaction of every average intelligence. They stand by the sentence: what is true must be provable and everyone must be able to understand it. The occultist, however, asserts nothing else than what any other scholar asserts in his own field, and he demands nothing more than every mathematician also demands.
