Because the change she describes is not a repair of her old life but the emergence of a completely new one — which is exactly what happens in a metamorphosis.
Read the extract’s own verb: she does not say she would recover or manage; she says she would “transform it to a world of limitless possibilities.” The caterpillar comparison holds at three points:
- The two possible endings. A caterpillar either stays a crawling grub or becomes a butterfly. Dr. Malik states her position in exactly that shape — “I had two choices—squander my life in remorse or transform it”.
- The still, closed stage in between. The surgery and the wheelchair are the cocoon: from the outside nothing appears to be happening, while the whole design of the life is being rebuilt.
- The new capacity at the end. The butterfly can do something the caterpillar never could — fly. She emerged able to do something the swimmer she used to be had never done: represent India at the Paralympics and win a medal in shot-put.
