Lo que la oruga interpreta como el fin del mundo, es lo que su dueño denomina mariposa.

You can chase a butterfly all over the field and never catch it. But if you sit quietly in the grass it will come and sit on your shoulder. 

The butterfly counts not months but moments, and has time enough. 

There is nothing in a caterpillar that tells you it's going to be a butterfly.

We are like butterflies who flutter for a day and think it is forever. 

In nature a repulsive caterpillar turns into a lovely butterfly. But with humans it is the other way around: a lovely butterfly turns into a repulsive caterpillar. 

Just like the butterfly, I too will awaken in my own time.
We delight in the beauty of the butterfly, but rarely admit the changes it has gone through to achieve that beauty. 

I do not know whether I was then a man dreaming I was a butterfly, or whether I am now a butterfly dreaming I am a man. "How does one become a butterfly?" she asked. "You must want to fly so much that you are willing to give up being a caterpillar."
