It is not growing like a tree (Poem)

"Is not growing like a tree
In bulk, doth make Man better be;
Or standing long and oak, three hundred year,
To fall a log at last, dry, bald and sere:
A lily of the day
Is fairer far in May,
Although it fall and die that night;
It was the plant and flower of light.
In small proportions we just beauties see;
And in short measures life may perfect be."

(JONSON, Ben. In O brilho de sua luz, de Danielle Steel)
