Won-Hyo, Weonhyo or Wonhyo--a remarkable man who lived from 617 to 686 A.D. He saw the end of the Three Kingdoms period and the beginning of the Unified Silla Dynasty. He was instrumental in introducing Buddhism to the Korean peninsula, and his philosophy was shaped by various doctrines of the time. Mahayana is one of the two or three major branches of Buddhism, and Won-Hyo sought to embrace not only all aspects of the various schools, but to integrate the various doctrines into a cohesive whole. His works include commentaries on the Awakening of Faith, Nirvana Sutra and Vajarsamadhi Sutra. He believed that opposites could be reconciled through a doctrine called One Mind, wherein "when the essence of Mahâyâna, or One-Mind, is unfolded, immeasurable and limitless meaning can be found in its doctrine. Conversely, when the doctrine is folded, it returns to its essence, which consists of two aspects: the absolute and the phenomenal." (SUNGTAEK CHO (1998). Buddhist philosophy, Korean. In E.
