Stream of Confucianism and a Study of Dongmu Lee Jema's Formation of Sasang through Hado and Nock-seo, along with Four Character and Seven Feeling Theory

According to Confucianism, the world before Confucius focused on respecting the heaven which meant that everything could be done by the heaven. After the period of Confucianism, Joo-Ja asserted that everything could be done by nature. During the Chosun Dynasty, philosophers such as Seo Kyung-duck, Lee Hwang, and Lee Yi talked about four characters and seven passions of human being. They started to focus more on the inside of human nature. During the later period of the Chosun Dynasty, a philosopher by the name of Dongmugong Lee Jema analyzed that one's nature and feelings can change his or her external matter and the function of internal organs by purity or impurity of one's mind. Based on these analysis, Dongmugong discovered 'sasangin' which puts more emphasis on one's state of mind compared to the outside the world. Also, Dongmugong tried to figure out the connections between Confucianism and medical science. If you use change fire and stone theory which is difference between hado and nock-seo to expain four seven theory one's mind could be define as four natural characters and seven feelings. From four seven theory four is ying and seven is yang. This is the method of cure and understand the structure of human body. And also, four natural characters and seven feelings can be divided into heaven and earth. You can see Four natural characters is far more similar to heaven and seven feelings are similar to earth. According to four-seven theory hado is permanent and you can find out 'sasangin' is permanent also. Since seven feelings are influenced by sam-jae, you can analogize there are 21 different types in 'sasangin'. An underlying principle should there be 28 different types of sasangin instead of 21 different types of sasangin but one quater of sasangin is hidden according to samhyuniljang theory. All creations in the world are organized by unification of the great absolute and symmetry distinction of yingyang. With these facts identity of the heaven, earth and man which is named samjae generates symbols of independent sasang. And also, sasang generates relations between five element, six energy and the six family relation. From six family relation comes seven feelings of man which creates a category of the eight trigrams for divination and unification of nine palace. All these process are united.
