Classic Poem

LET me not deem that I was made in vain,
Or that my being was an accident,
Which fate, in working its sublime intent,
Not wished to be, to hinder would not deign.
Each drop uncounted in a storm of rain
Hath its own mission, and is duly sent
To its own leaf or blade, not idly spent
'Mid myriad dimples on the shipless main.
The very shadow of an insect's wing,
For which the violet cared not while it stayed,
Yet felt the lighter for its vanishing,
Proved that the sun was shining by its shade:
Then can a drop of the eternal spring,
Shadow of living lights, in vain be made?
