Abstract

The essence of Daesoon  Thought consists of the tenets of Daesoonjinjihoe; Eumyanghapdeok, shininjohwa, haewonsangsaeng, dotongjinkyong. The first tenet of Daesoonjinrihoe, Eumyanghapdeok is the basis of the creeds, the purpose, the instructions and rules of Daesoonjinrihoe.
Eunyanghapdeok explains the development of the history by reconceptualizing the Eumyang thought. The literary interpretation of Eumyanghapdeok is the creation of new harmony by integrating the virtues of Eum (Yi) and Yang. The conversion from the relation of conflict to new harmony, through integrating the mutual virtues, can induce the cosmos, nature and human-beings into settlement and prosperity. To establish Eumyanghapdeok rightly, we must have the right Yang and the right Eum (Yi). Under the repression of Eum and the respect of Yang by the principle of mutual opposition (Sanggeuk), Yin and Yang cannot integrate the individual virtue rightly and they only accumulate their enmities. The expansion of enmities in the former Heavenly world is caused by this repression of Yin and the respect of Yang. Thus, Eumyanghapdeok must be done by the right Yin and the right Yang. The realization of Eumyanghapdeok by the right Yin and the right Yang can be possible by the removal of enmities to overcome and mutual opposition. To do so, we must appreciate mutual survival of helping others positively in the first hand and the benefits of others sincerely, and we must establish the respect for human-beings practically. The realization of Eumyanghapdoek is very necessary to solve the various problems of the former Heavenly world and to build the ideal world that the mankind has sought for.
