OK, since you picked butterfly, here's why though you didn't know you knew it.:-)
The Butterfly
"The butterfly is ever more blessed than other creatures of flight.
Though all grace the heavens in the ecstasy of flight,
the butterfly has known the drudgery of the crawl
and the lonely confinement of the cocoon.
His new found freedom is richer,
wilder and more thrilling than life itself.
This is the beauty of recovery."
