Many wuxia characters spend the first part of their lives as secular people, then end up becoming Buddhist monks or Taoists priests as they arrive at some kind of spiritual enlightenment. Hui Juk did it backwards: he spent the first part of his life as a Buddhist monk, fell for the temptations of the secular world, and finally gained all the fruits that secular life had to offer, including power and romance.
Even as a youth, however, Hui Juk did have a measure of uncommon enlightenment. It wasn't perfect, of course, and hence, he gave into temptations. One has to wonder, however, that if Hui Juk did live to a ripe old age, if he would have had a change of heart and decided to resume his search for enlightenment. We know that Hui Juk's sworn brother, Deun Yu, eventually gave up his royalty and his women to become a monk as per Dali royal tradition. Do you think the elderly Hui Juk followed suit and returned to the life of a monk in his later years?
