Perhaps it's a quantic formula to keep space-coherence and reality at balance. By means of certain behavioral patterns which ensure conscious development on life forms. The physic tree might had have an origin, but the encoded pattern of its ideal form is indefinitive. Existing without time and perception. Formless and undefined.

Through chaos comes challenge, growth, and self-discovery on said life forms. In this case, the main protagonists. I do believe the tree of harmony is all things.
