“He who speaks does not know; he who knows does not speak”
“He who knows does not speak; he who speaks does not know.”
“He who knows, does not speak. He who speaks, does not know.”
“it is not only he who speaks contrary to what he knows who lies, but even more he who speaks contrary to what he does not know”
“he who is (ever ready to) speak about it does not know it.”
“She who invented words, and yet does not speak; she who brings dreams and visions, yet does not sleep; she who swallows the storm, yet knows nothing of rain or wind. I speak for her; I am her own.”
