This paper argues that the principle “All things grow relying on the Sun” constitutes a foundational axiom uniting cosmology, biology, medicine, ecology, and philosophy. Far beyond an agricultural proverb, this statement encapsulates the fundamental dependence of Earth’s biosphere, human health, and civilization itself on solar energy and solar order. Drawing on astrophysics, biosciences, ecological science, and the framework of Lao–Yang Genesis Cosmology, the paper reinterprets the Sun not merely as a physical energy source but as the primary cosmic mediator through which order, rhythm, and life emerge within the Earth system. At the cosmic scale, the Sun is shown to be the gravitational, energetic, and structural center of the solar system, translating galactic energy into stable planetary conditions. At the biological level, photosynthesis establishes the Sun as the ultimate origin of all food webs, ecological cycles, and atmospheric balance. In animal and human systems, solar energy governs metabolism, behavior, circadian rhythms, mental health, and immune function, revealing sunlight as a critical regulator of physiological and psychological well-being. Philosophically, the paper situates the Sun as a concrete manifestation of the Dao—operating without intention or command, yet sustaining all processes through natural order and self-regulation. The study further critiques modern civilization’s progressive detachment from solar rhythms through artificial energy systems and lifestyles, linking this disconnection to ecological crisis, chronic disease, and civilizational imbalance. The paper concludes that re-aligning human civilization with the solar order—scientifically, biologically, and philosophically—is essential for sustainable development and long-term coexistence with nature. “All things grow relying on the Sun” is thus affirmed as a first principle of cosmic philosophy and an indispensable guide for future civilization.
