Abstract
The Buddhist and Daoist influences on the origins of the Taijitu and their influences on T’oegye’s philosophy are discussed. The notion of ji (tranquillity) is taken as an example on which the Neo-Confucianism debate and the limits of verbal representations are shown. T'oegye adherence to Zhu Xi in relying to the doctrine of mindfulness is taken into consideration as one of the central ones in the Ten diagrams, in contrast to Zhou Dunyi's emphasis on tranquillity. He followed the Zhu Xi's line in a direction of commenting the commentaries or a form. He strongly relayed on words, although as a supplement to the diagrams. By this hediminished the force of the cartography of spirit so central in Chinese Song Neo-Confucianism. In T’oegye is not calm and tranquillity per se, but a conscious and wakeful state of absolute mental quiescence - one of the polar conditions of consciousness.
