"The merry-go-round" [boomerang]

The night appears   the day appears   it's endless!
    the merry-go-round   is twirling all the time!
in such a swirl   the soul should not be friendless
    the line of thought   is rounded with a rhyme
    a moment seeking stillness   were no crime!
if I'm a pensive letter   where to send this?
    perchance the world is theatre   told in mime?
the night appears   the day appears   it's endless!
