"Yun Men said, "When you can't speak, it's there; when you don't speak, it's not there. When you can't discuss it, it's there; when you don't discuss it, it's not there." He also commented saying, "You tell me, what is it when you're not discussing it?" Fearing people wouldn't understand, he also said, "What else is it?""
