 Ŭisang 義湘 (625–702), a younger contemporary of Wŏnhyo and also from Silla, is the founder of Korean Hwaŏm (C. Huayan) school. His view is presented in his Ocean Seal Diagram (haeindo 海印圖) where Hwaŏm philosophy’s vision of reality and an all-embracing worldview is most perspicuously symbolized. Differences and distinctions are overcome in this work and shown to be integral parts of a transcendent whole. The nature and characteristics of this transcendent and cohesive vision of reality, however, were not easy for all Buddhists to understand. What we call “the universe” was simultaneously empty of duality and self-nature and yet still able to comprehensively integrate all things. Although proponents of the Hwaŏm school employ several terms to describe aspects of this reality, the most general and all-inclusive descriptive term is “perfect interfusion” (wŏnyung).
