Thus the seer, with vision clear,
Sees forms appear and disappear
In the perpetual round of strange
Mysterious change
From birth to death, from death to birth,
From earth to heaven, from heaven to earth,
Till glimpses more sublime
Of things unseen before
Unto his wondering eyes reveal
The universe, as an immeasurable wheel
Turning for evermore
In the rapid, rushing river of time.
Henry Wadsworth Longfellow.
