Because they seek Truth in a teachers words, they find none; for words are but signposts. They see his words, but not his meaning. They see his surface, but not his depths. Despite all this, the teacher remains stalwart, and refrains from using complicated arguments and rationalizations. He continues to speak simply, appears a simpleton, and is thus accused of incompetence.
He could weave beautiful philosophies and tell captivating stories, and the world would love him. But he has too much respect for life. He could display his power of intellect to all, and they would pronounce him a great man; but he has left reasoning behind. He is a catalyst for a chemical reaction which precipitates enlightenment - but you must provide the ingredients.
There are no words to explain the Truth. The more words you use, the farther you will be from it. Sometimes the sage remains silent; at other times he speaks. But when he does use words he refutes those very same words. In this way he uses words to convey Truth, without explaining it.
