다국어 초록 (Multilingual Abstract)

Taoism exercised its influence and has made much progress apparently under the aegis of the Tang dynasty. But since the external alchemy, a traditional way of eternal life that they have pursued, met the limitation, they were placed in a situation where they needed to seek a new discipline. From this period to the early North Song dynasty, three religions have established the unique theoretical systems of their own theory of ascetic practices. They showed their own unique formats as follows. Neo-Confucianism established the theory of moral training, Buddhism did the theory of ascetic practices and Taoism had theory of discipline. By this time, a person who claimed the Intermixture of Three Religions composed the new system of theory of ascetic practice by taking advantage of other religions and putting them into his own view. Chen tuan established the theory of internal alchemy of Taoism and was the most influential figure in the world of thought since North Song dynasty. He clearly declared that he accepted the merits of other religions in his theory. He added I Ching of Confucianism in I Ching of secret of Taoism to stop the logical gaps during the process of disciplines in Taoism and took ascetic practices on mind of Buddhism into his system while he sought a way to integrate the dual structure of body and mind. The theory of Chen tuan`s internal alchemy was training schema with stages of ``YeonJeongHwaGi``, ``YeonGiHwaSin``, and ``YeonSinHwanHeo`` based on the concepts of vital, energy and spirit. The internal alchemy practice that Chen tuan was saying started from the practice of Zen to keep the mind calm with the basis of fundamental principles of interpretation of book of change according to Taoism. When a person reached the state to be in concert with all changes at the end of the silence and be full of wisdoms, he finally returned to the state of BokGwiMuGeuk by taking the flow of subtle mind and transforming it into energy. He expressed this process by drawing ``MuGeukDo``. Oriental philosophy categorized human into ``phenomenal existence`` and ``original existence``. The logic of theory of ascetic practice has been established from these ``category of existence``. It would be determined whether it will return to ``original existence`` or be stepped up from ``phenomenal existence`` according to how the concept of ``self`` or ``I`` was made. Chen tuan who established the theory of internal alchemy in Taoism has established the unique theory of internal alchemy discipline and system of intermixture of three religions in this aspect. Today is called ``era of self-loss`` or ``era of incurable diseases`` caused by environmental pollution. It`s still meaningful to review the theory of discipline of Chen tuan`s connecting the body and the soul to heal the self, and keep life healthy and pursue the new way of discipline based on it.
