It (Tao) is eternally without desire. So, it can be called small. All things return to it, although it does not make itself their ruler. So, it can be called great.
LaoziActing without design, occupying oneself without making a business of it, finding the great in what is small and the many in the few, repaying injury with kindness, effecting difficult things while they are easy, and managing great things in their beginnings; this is the method of Tao.
Laozi
