Pain=Growth
I had a thought... when muscles are put to work they ache and are painful, the result is growth. Simple rappid addaptive concept, now if you apply it to the mind and spirit (energy) to this same concept, could the response be growth? Realizing the evil that exsist in the world and coming to find ones self, and admit ones own faults can be a mentally painful time. But embracing it can promote mental growth, ignorance is convient... One should not ignore ones own emotion. Learn from it. Kinda like diving into the darkness to see the light.
