This paper aims to explore the scholar’s practical discipline of Muljae An-ui who worked in Jungup area followed his teacher Iljae Il-hang’s instruction. He established 8 absolute self-disciplines in the politically neglected Jungup area, and spent his whole financial estate to practice the essential scholars’ attitude with his alumnus Hong-rok Sohn during the period of Imjin Japanese Invasion. This paper is based on the following historical records: his family documents, his tomb script, his book “Imgyegisa,” and the Palmuljam, the 8 absolute self-disciplines.
Through careful examination of his family documents, this study identified his child period name Choongryul, his adult period name Ui-sook, and his nick name Muljae and the fact that he was born in Gohyun-nay, Tae-in in Dec 6, 1529 during Joongjong 24th year. He studied under the guidance of his teacher Il-Jae Ih-hang and when Japanese troop invaded in 1592 and the king ran away, he mobilized volunteer troops with Hong-rok Sohn by following the will of his teacher, and collected three hundreds sacks of rice, silk, and fabrics to send them to the temporary loyal palace and volunteer troop camps. Afterward, he was actively involved in moving Taejo’s royal portrait and the “Sillok” the true record of the Yi dynasty with Hong-rok Sohn by the 300 oxcarts to the Dragon cave in Naejang mountain located in Jungup, and in July next year he moved them to Ah-san following the king’s instruction. In addition, during the second Japanese invasion in 1597 he safely moved them to a separate temple building in Myohyang mountain. His book “Imgyegisa” is a documentary record describing these two scholars’ faithful serving activities of moving the “Sillok” the true record of the Yi dynasty from Naejang mountain to the hands of Choongchung-do governor San-bo Lee during the whole period between June 22 of 1592 and July 24 of 1593. “Imgyegisa,” a book of two year record has been hidden in the history during the 420 years. But the book was finally discovered while tracking back the movement of the “Sillok” and following the record of “Wansanji” The book deserves the historical value because it was published in the politically neglected Jungup area. It is one of the very important historical documents along with “Honamjuluirok” recording the faithful fighting activities of the volunteer troops and soldiers during the Japanese and Chinese invasions. In particular, it is important to note that by following his teacher Il-jae Ih-hang, Muljae An-ui established the 8 absolute practical disciplines of the scholars which must have encouraged the next generation scholars to keep learning and practicing the disciplines to become volunteer soldiers and patriots in Jungup area. It proves well in the history that the leaders of Donghak Farmers’ Revolution, Bong-jun Jun and Gae-nam Kim, who encouraged the revolt in Samrye area to save the country, were also originated in Jungup area, and the 1906 year’s patriotic fighting movement which started in Moosung private school of this area after the 1905 year’s ordinance prohibiting topknots spreaded into nationwide. Thus, the scholar’s practical discipline established by Muljae An-ui in Jungup area must be reconsidered as a valuable cultural inheritance of Korea in modern days.
