Yes, the whole world is haunted! --Only is haunted? --No, it itself haunts, it is eerie through and through, it is the changing apparent- body of a spirit; it is a phantasm. What else is a ghost but an apparent body, but an actual spirit? Now the world is 'vain;' is 'empty;' is only dazzling 'appearance'; its truth is solely the spirit; it is the apparent-body of a spirit. Look around near or far, a ghostly world surrounds you everywhere; you always have 'apparitions' or visions. Everything that appears to you is only the appearance of an indwelling spirit, is a ghostly 'phenomenon'; the world is to you only a 'phenomenal world' behind which the spirit moves its essence. You 'see spirits.' Are you perhaps thinking of comparing yourself to the ancients who saw gods everywhere ? Gods, my dear modern, are not spirits; gods do not reduce the world to an appearance and do not spiritualize it. But to you the whole world is spiritualized and has become a mysterious ghost; so don't be surprised if you also find nothing but a phantasm in yourself. Doesn't your spirit haunt your body, and isn't the former alone the true and the real, the latter only the 'transitory, empty' or an 'appearance'? Aren't we all ghosts, eerie essences, who await 'deliverance' --that is to say, 'spirits'?
