Analysis of Most Sweet it is

.  Most sweet it is with unuplifted eyes
   To pace the ground, if path be there or none,
   While a fair region round the traveller lies
   Which he forbears again to look upon;
   Pleased rather with some soft ideal scene,
   The work of Fancy, or some happy tone
   Of meditation, slipping in between
   The beauty coming and the beauty gone.
   If Thought and Love desert us, from that day
  Let us break off all commerce with the Muse:
  With Thought and Love companions of our way,
  Whate'er the senses take or may refuse,
  The Mind's internal heaven shall shed her dews
  Of inspiration on the humblest lay.
