Within the Wonbulgyo Scriptures, Il-Won-Sang, the One Circle Image, is presented as the central symbol that gathers the whole of the teaching into a single, unadorned form. It is explained as the Dharmakaya Buddha, the formless and all-pervading Buddha-body that represents ultimate reality and the fundamental nature of the universe. As such, it is not a personal deity, but the unconditioned, absolute truth that underlies and sustains all existence. The circle’s completeness and lack of beginning or end point to the infinite, all-encompassing character of this reality.

At the same time, the Il-Won-Sang is described as the sign of the mind-ground, the original nature of all beings. It symbolizes the inherent Buddha-nature, the enlightened potential that is already present within every sentient being. To contemplate Il-Won-Sang is therefore to turn back toward this original mind, recognizing that the nature of one’s own mind and the nature of the Dharmakaya Buddha are not two separate things. In this way, the symbol quietly teaches that the source of all phenomena and the inner ground of awareness are of one taste.

The Wonbulgyo Scriptures also present Il-Won-Sang as the gate of the practice of true cultivation. As the object of faith and meditation, it becomes the standard by which practitioners shape their lives, guiding faith, understanding, practice, and attainment as a single integrated path. Through steady contemplation of this empty yet full circle, practitioners are led to see the non-dual nature of reality, where the transcendent absolute and its immanent presence in all phenomena are inseparable. Thus the One Circle Image functions not only as a doctrinal symbol, but as a living guide for realizing Buddha-nature in the midst of everyday life.
