Music And Sleep

These have a life that hath no part in death;
  These circumscribe the soul and make it strong;
  Between the breathing of a dream and song,
  Building a world of beauty in a breath.
  Unto the heart the voice of this one saith
  Ideals, its emotions live among;
  Unto the mind the other speaks a tongue
  Of visions, where the guess, we christen faith,
  May face the fact of immortality--
  As may a rose its unembodied scent,
  Or star its own reflected radiance.
  We do not know these save unconsciously.
  To whose mysterious shadows God hath lent
  No certain shape, no certain countenance.
