Laozi is traditionally regarded as the author of the "Daodejing", but this is disputed. It is one of the most significant books in Chinese cosmogony. Like other ancient Chinese philosophers, Laozi often explains his ideas using paradox, analogy, ancient sayings, repetition, rhyme, and rhythm. In fact, the whole book can be read as an analogy: the ruler is the self, and the others and empire are the body, senses, and desires.
