I don't know if it is the same concept but I would like to think so:
I heard a story once about a man who found a cacoon in his garden. He watched and studied the cacoon waiting for the butterfly living inside of it to emerge. Finally after what seemed like days, he noticed that it was ever so slowly coming out of it's shell. He pulled up a lawn chair and sat there watching this (possibly) once in a lifetime event. After what seemed like forever, he started to get worried. He saw the tiny little critter struggling and struggling and he knew he had to do something. He went to his shed, pulled out some rose pruners and proceeded to make a tiny little cut in the cacoon to help the butterfly out. It worked! It easly climbed out of the cacoon and he was really pleased with himself. He reclaimed his place in his lawn chair to watch it unfold it's wings and take flight. Once again forever passed before any action from the little critter. it just sat there, all fat and engorged... crinkled wings and all. After what seemed like an eternity, it all of a sudden fell from it's perch on the branch and died. He was puzzled and a little sad. "What happened?"... he immediatly went inside and googled it. He came to a site that explained what happened. When butterflies are emerging from their cacoon, the struggle that they must endure pushes their fluids down their body and forces it into their new wings. If it had been left alone, that "struggle" he was seeing would have actually made the butterfly stronger and would have allowed it to use the beautiful wings it spend so long creating in that cacoon.
Now this story is paraphrased by me so I am not sure that I got EVERYTHING right in it, but I have always felt that all life is the same way. If it was meant to be then nature would take it's course and the creature will be stronger because of it. This is a little off topic, but I believe the same is true for human babies as well when it comes to C-sections. But please don't flame me, I know that there is a time and a place for that sort of thing but I have friends who scheduled their babies to come early, and when they didn't, they just set up a time that was convenient for them (not their baby) and had it removed from their bodies. I think that is very odd and when the baby (or snake) is ready, it will come.
