Purpose of this study is to determine idealistic boundary of aesthetics ultimately pursued by investigation of aesthetic contemplative norm defined by traditional philosophical thought inherent in the Korean Dance. The aesthetic consciousness and mental boundary formed from aesthetic contemplative norm of the Korean Dance has created the beauty of harmony, personality, and nature. This includes the 'life characteristics' precious as a human being, 'individuality' to respect an individual, and 'wholeness' that seeks harmony of an individual and the whole. The idealistic boundary of aesthetics inside the beauty with such characteristics can be summarized as follows; First, 'Spirit-energy (Ijeonghapiljeok) boundary of aesthetics' means harmonious relationships between reason and emotion. Namely, it aims harmony and unification between rational boundary and emotional boundary with artistic spirit to follow profound harmony of nature and to pursue new things. Second, 'Life-oriented boundary of aesthetics' includes lively appearance of substantive nature in a mind. It reveals that the appearance of nature itself is the origin of beauty and that 'life characteristics' that being alive itself is beautiful are true beauty. Third, 'Transcendent boundary of aesthetics' contains spirit of the heaven. United aesthetics boundary is to realize the order of nature and to pursue harmony of the boundary between nature Taoism and dance spirit. Surreal time and space world in freewheeling state without any confinement in dance is the best idealistic aesthetics boundary crossing over boundary between human and the god, boundary between reality and unreality, and boundary between labor and play through freedom of deviation. As discussed above, 'Korean Dance's aesthetic contemplative norm and aesthetics boundary' contributes a clue to aesthetically determine the original form of Korean Dance theory and the development. Aesthetic consciousness and aesthetic dignity of a work, and 'idealistic aesthetics boundary' will identify aesthetic categories to determine aesthetic characteristics inherent in the Korean Dance.
