The heart of Seon (Zen) practice lies in the direct realization of one’s true nature, often spoken of as Buddha-nature or original mind. This realization is not understood as acquiring something new, but as awakening to what has always been present at the deepest level of being. To “see into one’s true nature” is to awaken to this original Buddha-nature, which is identical with enlightenment or awakening. Such realization is said to end fundamental ignorance and reveal a wisdom that is already inherent, though ordinarily obscured by delusion and confusion.

This awakening is characterized by a direct, intuitive understanding of reality that transcends conceptual thinking and dualistic perception. Rather than relying on discursive thought or abstract doctrine, Seon emphasizes an immediate experience of reality “as it truly is,” beyond the illusions created by the discriminating mind. In this sense, the practice aims to break through all mental constructs and attachments, allowing a state of non-dual awareness to manifest, where rigid distinctions between self and world no longer dominate experience.

Within Korean Seon, this process is often pursued through intensive meditation, especially questioning meditation known as ganhwa seon, which employs hwadu or critical phrases. These meditative inquiries are not meant to be solved intellectually, but to exhaust habitual patterns of thought and drive the practitioner toward a direct breakthrough. When this breakthrough occurs, enlightenment is understood as the clear recognition of one’s inherent Buddha-nature, beyond birth and death, form and emptiness. From this realization, awakened wisdom and compassionate activity naturally express themselves in the fabric of everyday life.
