M. C. Escher's self portrait.

"Those who grew up in the torment bite, bites. Painfully scorched in the sad dry earth, how can I be detested for my spite when I inflict pain?"

"Beat me, until the destruction, beat!"
"Inwardly, I am hard and cold, there is no glow or fire in me, but if I am struck by fate, the sparks fly everywhere."
