rather than impute to your beloved a levity of sentiment that would seem
to you a treason, you accept the chimera of 'magical fascination.' In
this frame of mind you sit down to read the memoir of a mystical
enthusiast. Do you begin now to account for the Luminous Shadow? A
dream! And a dream no less because your eyes were open and you believed
