Every great poem is in itself limited by necessity, — but in its suggestions unlimited and infinite. - Henry Wadsworth Longfellow

Talk not of wasted affection, affection never was wasted;
If it enrich not the heart of another, its waters, returning
Back to their springs, like the rain, shall fill them full of refreshment;
That which the fountain sends forth returns again to the fountain.

Lives of great men all remind us
We can make our lives sublime,
And departing, leave behind us
Footprints on the sands of time;

When we reflect that all the aspects of Nature, all the emotions of the soul, and all the events of life, have been the subjects of poetry for hundreds and thousands of years, we can hardly wonder that there should be so many resemblances and coincidences of expression among poets, but rather that they are not more numerous and more striking.
