The Wonbulgyo Scriptures arise first and foremost from the awakening and teaching activity of Pak Chung-bin, known by his dharma name Sotaesan, the founding master of Won Buddhism. His enlightenment experience and subsequent guidance provided the core doctrinal content that later came to be recognized as the scriptural foundation of the movement. In this sense, the scriptures are not merely a literary product, but the crystallization of a lived spiritual realization expressed in words, practices, and institutional forms. The teachings he articulated became the wellspring from which the entire tradition of Won Buddhism flows.

At the same time, these scriptures did not emerge in a vacuum or as the work of a solitary figure alone. Sotaesan’s disciples played a crucial role in recording, organizing, and preserving his words, dialogues, and instructions. After his passing, the task of systematically compiling and expanding the Won Buddhist Scripture (Wonbulgyo kyojon) was carried forward especially under the guidance of his successor, the second patriarch Song Kyu, known as Chongsan, together with other leaders of the order. Thus, the Wonbulgyo Scriptures can be seen as both the direct expression of Sotaesan’s realization and the careful, collective effort of his disciples to give that realization a durable, coherent textual form.
