Everything in Tao exists in a synchronistic relationship. Tao transmits the breath of life that powers the universe. It is considered that the Tao surrounds the universe and transmits different patterns of energy into the universe. The macrocosm communicates with the microcosm, and different patterns might affect and reorder seemingly unrelated events in the outer world.
Imagine that destiny has a variety of patterns (chin. 理 li) which can create the  shapes and behaviours, alike genetic repository, or universe's DNA. When expressed in living matter, the universe’s DNA manifests as an organic DNA. Therefore implementation of the Book of Changes about a thing can be like searching individual DNA in order to discover the segment of genetics currently running. 
Taoism believes that the visible universe (Chin. 太極 or taiji) is a manifestation of the cosmic mother (Chin. 無極 wuji) and is destined to return to nothingness  (Chin. 無 wu).
The universe’s DNA do not absolutely determine the future, because the patterns from the cosmic mother can change the current order and introduce overwhelming forces that usurp destinies. 
Each thing in the universe is in a state of inaction (Chin. 无为 wu wei) – which means harmony with the patterns, or do nothing and let things take their own course.
