天人合一Unity of Heaven and Humanity

“Unity of Heaven and Humanity” (Tian Ren He Yi) represents one of the most holistic and ultimate concepts in Chinese philosophy, emphasizing the integral connection between humans, nature, and the cosmos. This paper asserts that Tian Ren He Yi should return to the Daoist origin in Laozi and Zhuangzi, removing the Confucian overlay of moral-political interpretation, to reestablish the ontological and spiritual link between humans and the universe. Building on the Lao-Yang Genesis Cosmology, this paper proposes that Tian Ren He Yi is not only a philosophical ideal of inner cultivation but also a systematic framework for dialogue with modern science, ecological crises, and cosmic evolution. The discussion proceeds through five dimensions: ontology, philosophical comparison, scientific dialogue, life realization, and civilizational practice, providing theoretical and practical guidance for ecological civilization and sustainable social governance.
