Immediately upon seeing Daewon sunim, one of the monks named Beopseong (presently known as the Zen Master Jinje, a disciple of Zen Master Hyanggok), called out to him, "Say something about Bodhidharma's 'I don't know.' Kong-an (Koan)." Daewon sunim answered without a moment's hesitation, "Revealed." Songam sunim, who was standing nearby asked him about the Ansujeongdeung Kong-an (Koan), "How would you save yourself?" Daewon sunim spoke loudly, "An (岸)! Su (樹)! Jeong (井)! Deung (藤)!" All the gathered monks stood still with their lips pursed in silence as Daewon sunim turned around and walked away. The next day after breakfast, Myeongheo sunim, who was serving as monitor for the retreat, called a temple hearing to find out why the monks had been absent without notice the night before. During the hearing, all that had happened up on the mountain was laid out in the open and as a result, the monks who had been absent during the sitting meditation session assumed their formal robes and bowed in penance before Zen Master Jeongang, who was serving as the Josil of the temple at the time. The next day, Zen Master Jeongang called on Daewon sunim. He told Daewon that his first Song of Enlightenment was clear evidence of his enlightenment but that a Song of Enlightenment is customarily kept short. To this, Daewon sunim recited the second Song of Enlightenment he had composed when he saw the sun and the moon in the setting sky while passing the fields of Gimje. After Zen Master Jeongang heard the second Song of Enlightenment, he again asked Master Daewon to make up another song on the spot that would encapsulate the same stage of enlightenment. Immediately upon this request, Master Daewon produced the following song:  Zen Master Jeongang listened to the first two lines with his eyes gently closed; then upon hearing the last two lines, he opened his eyes, revealing delight. However, he did not stop there and asked once more, "When the others called you out on the mountain and Beopseong asked you to speak on the 'I don't know.' Kong-an (Koan), you said, 'Revealed.' If you were Emperor Wu of Liang, how wouldyou respond to Bodhidharma's 'I don't know.'?"
