The Dao as such is pointed to two types of wisdom: practical and sagely, which are embodied in three distinct but interrelated types: the Dao of Heaven, the Dao of man, and the Dao of the sage. By contrast, the Dao of Heaven is set up as a ideal frame of reference. The Dao of the sage follows the Dao of Heaven for the sage himself is acting for all but never for himself. The Dao of man is just the reverse of the Dao of the sage because of its self-interestedness. In most cases, the Dao of human existence is likely to slant toward either the Dao of man or the Dao of sage. In Laozi, the Dao of human existence is oriented toward the Dao of the sage and associated with sagely wisdom when it is applied to the human condition and living experience.
