"In any case, once you're dealing on a nonverbal level, ambiguity is unavoidable. But it's the ambiguity of all art, of a fine piece of music or a painting - you don't need written instructions by the composer or painter accompanying such works to 'explain' them. “Explaining” them contributes nothing but a superficial 'cultural' value which has no value except for critics and teachers who have to earn a living."
