Return is the movement of Dao. Fan, ben ye. Ben is the origin, the reason why Dao moves; when it moves, myriad things are generated; to turn away from it leads to destruction. The weak is the function of Dao. Softness and weakness are what Dao commonly employs, hence they can endure forever. All things under heaven and earth are born from the existent; all myriad things under heaven originate from Heaven and Earth; Heaven and Earth have form and position, hence it is said they are born from the existent. The existent arises from the non-existent. Heaven, Earth, spirits, and clarity, as well as tiny crawling creatures that fly or move, all arise from Dao. Dao is formless; hence it is said to be born from the non-existent. This means that the fundamental surpasses the ornamental, weakness surpasses strength, and humility surpasses arrogance.
