Seon presents mind and body not as two separate substances but as different aspects of a single, unified reality. The apparent division between the mental and the physical is treated as a conceptual convenience rather than an ultimate truth. Both mind and body are understood as expressions of Buddha-nature or “One Mind,” arising together in dependence on causes and conditions. Thoughts, emotions, sensations, and physical form are thus seen as various manifestations of the same underlying nature. From this perspective, the usual sense of a mind “inside” a body is regarded as a misunderstanding of how experience actually unfolds.

This non-dual view is not merely theoretical; it is verified and embodied through practice. In seated meditation and walking meditation, posture, breathing, and bodily awareness are not secondary supports but integral dimensions of awakened presence. The body’s stillness or movement and the mind’s clarity are cultivated together, revealing their inseparability. Ordinary activities—eating, walking, working, temple chores—are likewise treated as direct fields of practice rather than distractions. In this way, enlightenment is understood as involving the whole being, where body-and-mind function as one continuous, integrated process.

From the standpoint of realization, the distinction between mind and body falls away, and experience is known before such dualistic categories arise. Yet within everyday life, their interdependence is still acknowledged: mental states shape bodily experience, and bodily conditions influence the mind. Practice in Seon therefore attends to both intention and conduct, inner clarity and outward behavior, as mutually conditioning aspects of a single path. What emerges is a vision of human existence in which mind and body are distinct in function but not separate in essence, each revealing the other as facets of one undivided reality.
