An essay by Ryan Bongseok Joo:
"Western Buddhists, who were introduced to Korean Seon (Jp. Zen, Ch. Chan 禪) Buddhism through Seung Sahn sunim (1927-2004), might find it surprising that gong’an (Jp. kōan 公案) meditation practice is taught quite differently in Korea from the way Seung Sahn sunim trained his disciples in the West. For instance, Seon masters in Korea generally do not ask their student to resolve a series of different gong’an gates like the way Seung Sahn sunim did. Instead, meditating on a single gong’an is considered sufficient in itself to bring the student to full awakening. It is also not a common practice to allot one-on-one private interview (Jp. dokusan 独参) time with a Seon master as part of the daily training schedule in a Korean monastery; although students can certainly meet with their teacher after having a breakthrough experience or when facing a difficult internal obstacle outside the regular monastic schedule. For native Korean Buddhists, it has been an open secret that Seung Sahn sunim heavily adopted the Japanese Rinzai Zen style in his teaching of gong’an practice, which was familiar to his Western disciples, but foreign to most Korean Buddhists. In this paper, I would like to introduce the other side, the teachings of gong’an practices by contemporary Korean Seon masters in Korea, which would be familiar to Korean Buddhists, but probably new to many Western readers."
