Within the Won Buddhist tradition, the scriptural corpus centers on a set of texts that gather and systematize the teachings of Sot’aesan (Pak Chung-bin) and his early successors. At the heart of this corpus stands what is often rendered as the Principal Book or Sacred Scripture (*Jeongjeon*), which contains the fundamental doctrines and practical guidance that define the movement’s spiritual path. This text presents the essential teachings in an organized fashion, outlining the vision of awakening and the method of practice appropriate to modern life. Alongside it stand doctrinal collections sometimes referred to as teaching scriptures, which further articulate and clarify the core principles.

The internal structure of the Principal Book is itself a map of the Won Buddhist way. It includes an account of great enlightenment, a general outline of practice, and sections that gather the essential dharma into a form suitable for repeated contemplation. Further portions address cultivation and inquiry, inviting practitioners to examine mind and conduct in a disciplined manner. Other sections turn explicitly to daily applications, showing how the teachings are to be woven into ordinary activities rather than reserved for secluded practice alone. In this way, the scripture functions not only as a doctrinal authority but also as a manual for lived spirituality.

In addition to these central materials, the scriptural body includes a text known as the Great Master’s Scripture (*Daejonggyeong*), which preserves more detailed records of Sot’aesan’s teachings and conversations. This work complements the more systematic Principal Book by presenting the founder’s words in a vivid, dialogical form, allowing readers to see how doctrine emerges in response to concrete questions and situations. Together, these texts form a canon that emphasizes both clarity of principle and flexibility of application.

Finally, the Won Buddhist scriptures are accompanied by various instructional, liturgical, and ceremonial writings composed by early masters. These materials do not stand apart from the core canon so much as extend it into the rhythms of communal worship and personal cultivation. They guide practitioners in embodying the teachings through ritual, ethical discipline, and shared practice. Taken as a whole, this scriptural constellation reflects a deliberate effort to harmonize timeless Buddhist insight with the demands and possibilities of contemporary life.
