If he does not wish to trouble his head, he can comfortably accept the appearances of things; but then he will be living only in the comfort of illusion. If however he wants to ferret out what is real in existence he must put himself to some trouble. He must persevere, read and re-read these pages until the meaning of it all dawns suddenly upon him, as it will if he does. It is perfectly natural for man to regard as the highest reality the experiences which impress themselves most forcibly upon him, which are those gained externally through his physical senses, and to regard as but half-real the experiences which impress themselves least forcibly upon him, which are those created internally by his own thoughts and fancies. But if he can be brought, as a true metaphysics can bring him, to arrive intellectually at the discernment that when he believes he is seeing and experiencing matter he is only seeing and experiencing thought, and that the entire cosmos is an image co-jointly held in the cosmic and individual minds, he will not unconsciously set up all those artificial resistances to the mystical intuitions and ultramystical illuminations which wait in the future for him.
