The purpose of this study is to interpret One Mind's Two Aspects and Three Greatness view in the Muae-mu of Won-Hyo as the same principle in dance, and to examine the essence and the underlying meanings of its phenomena. To this end, research focuses on One Mind's Two Aspects and Three Greatness of Won-Hyo through Awakening of Faith in the Mahayana. The implications for Muae-mu as a representation of One Mind are as follows. First, Muae-mu makes representation of One Mind as a part of phenomena and essence. One Mind's Two Aspects Muae-mu is a phenomenon to which the principles of body, form, and action are applied. Second, Muae-mu is a communication and healing dance as a means of popularization through art. Third, the ultimate goal of Muae-mu is to deepen insights of human beings and to return to their inherent nature. Fourth, it seeks concrete actions on a daily basis through the practice of One Mind. Fifth, it encompasses 'magnetization' and 'indigenization' based on Won-Hyo's enlightenment. Sixth, the aesthetic value in the art can be identified with human value in that it represents the human mind and philosophy. Dance is not an idea but a lived dance of living. This study suggests that the sincere and essential mission of dance is to vitalize the sense of living within the ever-changing world and to make a whole-person language of the body that combines the substance and the phenomena.
