This study analyzes the ways in which the "Sungju-Muga," the Korean Shamantic epic, presents its three subjects, "Sungju-Shin"(God of House), Shaman the medium of the epic, and people. Many criticisms have focused on the narrative-part where "Hwangwooyang," the main character of this epic, appears, whereas the actual "guts," the ritualistic performances of the work, present the prayer-part more frequently. This study, however, argues that the two parts, narrative-parts and prayer-parts, should be integrated together to create the complete meanings of "Sungju-Muga." "Sungju-Muga" is divided into three different parts of the three subjects claiming their domains: (1)the domain of the divine entity, "Sungju-Shin" (2)the domain of "Seseup-mu"(hereditary shaman), "Hwaraingi," and (3)the practical and realistic domain of ordinary people pursuing their desires through the "Sungju-Muga." "Sungju-Muga" obtains the complete meaning when both prayer-part and narrative-part are integrated together. This integration makes it possible that the three subjects of the "gut," God-shaman-people, can secure their domains. Yet the more the presence of God and sharman get disappeared in people`s recognition today, the more "Sungju-Muga" focuses upon the realistic domain of people`s desires. In modern society, "Sungju-Shin," "Sungju-Gut," and "Sungju-Muga" exist in the much realistic domain called "House-Home." Thereby even without their divine and shaman characteristics, faiths and expectations for "Sungju- Shin" will last for a long time.
