Analysis of A Vision of Rest

Some day this quest
       Shall cease;
          Some day,
          For aye,
    This heart shall rest
      In peace.
Sometimes—ofttimes—I almost feel
The calm upon my senses steal,
So soft, and all but hear
The dead leaves rustle near
And sign to be
At rest with me.
Though I behold
  The ashen branches tossing to and fro,
  Somehow I only vaguely know
The wind is rude and cold.
