"We will be at cross purposes in our correspondence until it has been made entirely plain that occult science has its own methods of research as fixed and arbitrary as the methods of its antithesis physical science are in their way. If the latter has its dicta so also has the former; and he who would cross the boundary of the unseen world can no more prescribe how he will proceed than the traveller who tries to penetrate to the inner subterranean recesses of L'Hassa—the blessed, could show the way to his guide."
