This thesis is a first step examine the Sa-san inscription. The style of this inscription is a Byunryen style close to archaic texts. It shows that Go-un himself is freeing from the form of Byun-ryeo style. In way of describing sentences, he follows that of Confucian. Appearance of Sa-chae(詞體) from Myung-sa(銘詞) represents a changing course of style; the recovering course from Byun-mun to Go-mun. Therefore, a perfect Byunryeo can`t appear, and hid style leans toward Go-mun rather than Byunryeo-min. The construction, largely, is divided into five paragraphs. The fist paragraph is perface, the second and the third paragraphs the body, the fourth Pyung-gyeol, and the fifth has a form of Chu-gi. That he describes divided into five paragraphs is related with the thoughts of the Five Elements. With the third paragraph as the central paragraph, he constructs the fore and the back symmetrically. Constructing the second and the fourth paragraph into eight paragraphs is borrowed from the dight stages of attainment of Nirvana. Dividing the third paragraph into twelve paragraph is based on the theory of twelve karmas. Just like this division of paragraphs, the paragraphs itself contains a comprehensive meaning. The inscription corresponds to the fourth paragraph, its meaning suggest core contents aforementioned. His consciousness in this inscription is two. The first is external consciousness, a sense of subjectivity. The second is inner consciousness, empbasis on the universality of human beings. In this inscription, he lays emphasis on harmony and positives rather than disunion and negatives. The third thing is an emphasis on the acquired education of human beings. That is to say, he lays emphasis on the purification of human feelings than maintenance of the original nature af human beings.
