The Tale of Master Namgung

This is the complete English version of MeKorean’s modern Korean retelling of the main scenes. It is not an official ITKC translation or a line-by-line scholarly translation. Consult the Classical Chinese original for its precise wording.

Namgung Du grew up in a wealthy family in Impi. His ancestors had been reluctant to enter office, but he sought a name through study and the examinations. At thirty he passed the sama examination and became known in the examination halls for his writing. He was proud of his talent, but harsh and stubborn in character. He treated villagers high-handedly and failed to show officials proper courtesy, steadily making enemies.

Even after moving his household to Seoul, Namgung Du returned to oversee the farms and property in his hometown. A concubine whom he favored and had taught to read, write, and calculate remained at the country house. One day he returned unexpectedly and found her with a male relative. Suppressing his anger, he hid and watched before taking a bow and arrows hanging on the wall. He shot and killed them both, buried their bodies in a ditch in the rice fields, and hurried back to Seoul.

What he concealed came to light. Someone discovered the bodies and informed the bereaved families, and the case reached the authorities. Officials who had long resented Namgung Du also seized the chance to settle personal grudges. He was arrested, brutally tortured, and taken away under guard. His wife followed with their young daughter, got the guards drunk, and freed him during the night. But after he escaped, his wife and daughter were imprisoned and died there. The family's property was dispersed as well.

Namgung Du entered the mountains, shaved his head, and became a Buddhist monk. Taking the religious name Chongji, he observed a strict way of life, but again had to leave to evade his pursuers. Moving among temples, he encountered a young monk. The monk correctly identified his aristocratic background and even knew that he had killed two people and was on the run. Astonished, Namgung Du asked for instruction. The young monk told him that his own teacher, who possessed far greater abilities, lived on Chisang Mountain in Muju.

Namgung Du followed that advice into the mountains, but the teacher did not appear easily. He searched temples and valleys scarcely accessible to people for a year. Just as he was about to turn back, he saw a large peach stone floating down a stream through the woods. Following the water upstream, he found a house built against a cliff. A young attendant greeted him, and an old monk as gaunt as withered wood came out of a room. Namgung Du prostrated himself and begged to be taught.

At first the old monk pretended not to know what he meant and shut the door. After Namgung Du refused to leave for several days, he finally called him inside. The room held only a wooden pillow, a few books, and locked cupboards. Recognizing Namgung Du's strong endurance, the monk said he was better suited to learning how not to die than to other arts. He first made him resist sleep and repeatedly read Daoist scriptures. In the story, Namgung Du follows these instructions, enduring extreme fatigue and hunger.

The teacher gradually reduced his food and made him stop eating grain. He then used other foods in a regimen intended to transform the body. Namgung Du persevered through blurred vision and painful sores all over his body. After several years he learned to recite scriptures, count his breaths, and circulate his vital energy. The account presents this as an unusual discipline for becoming an immortal. As time passed, Namgung Du moved further from worldly thoughts and nearer to the expectation of attaining the Way.

But his mind faltered at the final stage. Sitting in training as his teacher directed, Namgung Du felt a mysterious change within his body. Believing success was close, he suddenly wanted to achieve it faster. At that moment he lost control of his energy and ran out screaming. The teacher calmed him and cared for him for a long time. He lamented that, despite years of teaching and endurance, a single impatient thought had ruined what was almost complete.

The teacher said that although Namgung Du had not reached the state of ascending to heaven, he could still become an immortal who lived long on earth. Asked about his own past, the old monk said that he had been born centuries earlier, encountered miraculous medicinal plants and scriptures, and trained himself. He remained in the mountains because he was charged with governing various deities of the East. Namgung Du also reported seeing dazzling light radiate from his teacher's body and, on the fifteenth day of the first month, witnessing a whole valley illuminated by lanterns as countless deities and strange beasts assembled.

At that gathering, the deities spoke of a great war that would strike this land. Namgung Du's account joined the order of the gods to disasters in the human world. His teacher later sent him down the mountain. He urged him to refrain from killing, sexual misconduct, and theft, and never secretly harm others. Above all, he said, cultivating the mind required honesty. Namgung Du wept as he said farewell. Looking back on his way down, he could no longer see the house where he had stayed.

He returned to the world, but his old life was gone. His country house had disappeared, and the fields had changed hands several times. At his Seoul home, only the foundation stones lay scattered in the weeds. He went to find a former household servant in Haenam. At first the man did not recognize him; when he finally realized who he was, they wept together. With that household's help Namgung Du established a new family and had a son and a daughter. He continued to remember his teacher's words, living in a deep valley and hoping to meet him again.

Later, when Heo Gyun had left his post in Gongju and was staying in Buan, Namgung Du came to visit him on foot. He said he was eighty-three, but looked about forty-six or forty-seven. Heo records that his sight, hearing, and strength had not declined. Namgung Du passed on scriptures and described his mountain experiences in detail. He said that steady cultivation could still bring a long life. Seeing that Namgung Du ate and lived like an ordinary person, Heo asked why.

Namgung Du answered that he had originally wanted to ascend to heaven, but had failed through impatience. Then he spoke of another side of longevity. In the mountains, solitude was painful; when he came down among people, he knew no one. The young dismissed him as an old man, leaving little pleasure in worldly life. People wanted to live long to enjoy happy things, he said, but what was the point of longevity without happiness? He also expressed a wish to spend his remaining years with his grandson and complete the life allotted to him.

He repeatedly told Heo Gyun that endurance was what must be maintained to the end. His teacher had recognized him as someone who could endure, yet his failure to do so at the last had brought him to this point. After staying for several dozen days, he brushed off his robes and left. Closing the account, Heo Gyun writes that it is unclear whether the history of the teacher Namgung Du related can be fully believed. Yet the age and health he himself observed are not easily explained either. Leaving both wonder and doubt in place, he regrets a life that lost an almost completed achievement through haste.
