Every caterpillar can become its own butterfly, but before it becomes a butterfly, it will first become a pupa bound by cocoons. In the cocoon, in the face of self-created pain, any attempt to struggle and change is futile. Pupa has only one choice, that is, to give up all resistance, accept the present feeling completely, and wait calmly until one day it breaks out of its cocoon and becomes a butterfly. Find a heart to love you at your lowest point, find a pair of hands to hug you at your most vulnerable point. It is a hero who can defeat the enemy and a saint who can defeat himself. Heroes defeat enemies, saints have no enemies.
