In the Seon tradition, meditation stands as the central discipline through which one directly realizes Buddha-nature and cuts through delusion. Rather than emphasizing conceptual study, it functions as a path of immediate, experiential insight, often described as “seeing one’s true nature.” Through this practice, the practitioner seeks to transcend discursive thought and encounter reality as it is, not as it is filtered through habitual patterns and views. Meditation thus becomes the primary means by which the mind’s inherent clarity and emptiness are revealed.

A distinctive feature of Korean Seon is the method known as ganhwa Seon, or questioning meditation, in which one focuses intensely on a gongan (koan) or its hwadu, the “critical phrase.” This concentrated inquiry—often on questions such as “What is this?” or “Does a dog have Buddha-nature?”—generates a profound sense of “great doubt” that undermines ordinary thinking and can precipitate a breakthrough of understanding. In this way, meditation is not passive quietism but an active, penetrating investigation into the roots of self and reality. The unification of deep concentration and insight is cultivated so that discriminating consciousness is cut through and non-dual awareness can emerge.

Alongside such questioning practice, Seon also values forms of sitting in open awareness, sometimes described as silent illumination, where the mind rests without clinging to specific objects of attention and its natural luminosity can manifest. Across these methods, meditation develops single-pointed concentration and stabilizes the mind, making it capable of sudden awakening. Yet its role does not end with formal sitting; the clarity and insight realized on the cushion are meant to permeate walking, working, speaking, and all daily activities. In this way, meditation serves as the central transformative discipline through which one’s original nature is both realized and gradually embodied in the ordinary flow of life.
