1) Nature consists of various units (physical, biological, animal, human) that are interconnected and interdependent. There is harmony among the first three orders as each provides for the others' needs.
2) Existence can be understood as the co-existence of units submerged in infinite space. Units are active and limited, while space is inactive yet all-pervading. Being in space, units are energized, self-organized, and recognize relationships with other units.
3) There is an overall harmony in existence as units interact in a mutually fulfilling manner. However, human beings currently exploit rather than enrich nature due to a lack of understanding of interconnectedness.
