Levels, Relations, Structures, and Organizations——Four Dimensions for Understanding Existence in the Universe

The "Triunity" framework consists of three core layers: ontology (Information-Energy-Situation as a unity), epistemology (Perception as Existence), and morphology (Seven Observations). Among these, the sixth observation, "Hierarchical Reality," states that the universe is composed of multiple layers of structure, with levels and structures as one. This paper extends and deepens the sixth observation. This paper proposes that levels, relations, structures, and organizations are four fundamental dimensions for understanding existence in the universe. They are not four independent concepts, nor are they four functionally divided "parts," nor are they fragments that need to be "combined" to form a whole—rather, they are four textures of the same existence itself. Any existence is simultaneously a complete fabric of these four dimensions: it is constituted by smaller levels, relations, structures, and organizations, while at the same time continuously coupling with larger levels, relations, structures, and organizations. Constitution and coupling occur simultaneously, without ever ceasing. The four dimensions appear undivided yet are actually distinguishable; they are mutually independent yet mutually immanent. This paper seeks corroboration from the natural world, physics, mathematics, and complex systems, demonstrating that these four dimensions appear simultaneously and inseparably across different fields. It further elaborates on their answers to the two fundamental questions: "why is existence real" and "how is existence understood."
