《老子》描述了一种极为玄奥的生命至境:得大道,不但可长生久视,还能具有终极智慧。然而如何通达其道境,才是人们最为关心,也是最为关键的问题。遗憾的是,《老子》一书并未对此作专题、详致的论述,其中方法显得零散而又含糊。及至目前,几种较为知名的注疏也属欲言又止、朦胧难会。 “Lao Tzu” describes a very mysterious life to the environment: avenue, not only long-term perspective, but also has the ultimate wisdom. However, how to reach its frontier is the most concern and the most crucial issue for people. Unfortunately, the book Lao Tzu did not make any special and detailed expositions of the book, in which the method seems fragmented and ambiguous. And up to now, several more well-known annotation is also unspeakable, hazy difficult.
