Locked into the cocoon, the caterpillar could not add or change anything about the physical aspects of its body... so it must have been how those physical aspects are organized... something beyond the visible... something you could call "spiritual".
I can teach you to speak butterfly, so you can fly like a butterfly.
The secret between being a caterpillar and a butterfly is in the speaking.
The saying so many people are coming to my site for is: you cannot talk butterfly language to caterpillars.
Now, the truth is: you cannot. The caterpillars out there won't hear it. Won't respond to it.
