A man found a cocoon of a Spicebush Swallowtail Butterfly. He took it home so that he could watch the Butterfly come out of the cocoon. On the day a small opening appeared, he sat and watched the Butterfly for several hours as the Butterfly struggled to force the body through that little hole.
Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no farther. It just seemed to be stuck. Then the man, in his kindness, decided to help the Butterfly, so he took a pair of scissors and snipped off the remaining bit of the cocoon. The Butterfly then emerged easily. But it had a swollen body and small, shriveled wings. The man continued to watch the Butterfly because he expected that, at any moment, the wings would enlarge and expand to be able to support the body, which would contract in time. Neither happened! In fact, the little Butterfly spent the rest of its life crawling around with a swollen body and shriveled wings. It never was able to fly.
What the man in his kindness and haste did not understand was that the restricting cocoon and the struggle required for the Butterfly to get through the tiny opening was the way of forcing fluid from the body of the Butterfly into its wings so that it would be ready for flight once it achieved its freedom from the cocoon. Freedom and flight would only come after the struggle. By depriving the Butterfly of a struggle, he deprived the Butterfly of health.
