He thought that at any time, the butterfly might expand the wings, shrink the body and the wings could support the body. Unfortunately, neither the wings expanded or enlarged nor the swollen body reduced.
Unfortunately, the butterfly just crawled around with withered wings and huge body. It was never able to fly all through its life.
Although the man did it with good intention, only going through the struggles the butterfly would have emerged like any other beautiful butterflies! The continuous effort from the butterfly to come out of its cocoon would let the fluid stored in the body convert into wings. Thus, the body would become lighter and smaller and the wings would be beautiful and large.
If we don’t want to undergo any struggle, we won’t be able to fly!
