YongSeong led the Korean Buddhist circles as a presentative Seon Master of the 19th century and expressed his enlightenment in various ways. His edification developed into practical outcomes such as translations, writings, and missionary works. In religious propagation, communication is a precondition. Focusing on this point, this paper attempts to understand YongSeong’s achievements from the perspective of communication. Specifically, this paper explores his early work, the Gwiwonjeongjong. The Gwiwonjeongjong is the first written work that refutes the defamation of Buddhist doctrines by other religions, which is also regarded as YongSeong’s first book with the obvious intent of communicating with people. The use of sophisticated logical structures, rhetorical situations, and expressions makes it easy to observe the elements of persuasive communication in his message. Thus, this paper analyzes the structure of the Gwiwonjeongjong by adapting the theory and methodology of ancient rhetoric and persuasive communication. Based on this analysis, the author found that the exquisite persuasive structures that appeared in the Gwiwonjeongjong allow it to be effectively persuasive. YoungSeong’s success is due to his efforts to actualize his enlightenment within the logical frameworks of Sutra. He develops his logic, not for himself, but to save all sentient beings. Considering this purpose different from that of common logic, he assuredly succeeds in expressing the Buddha’s communicational point of view. In addition, he reveals his own perspective on Seon communication with trans-logicality. As an attempt to modernize his enlightenment, this analysis is far from being complete but is worthy enough to provide a new way of sharing it. Research on YongSeong’s perspectives of communication will certainly contributes to our lives and practice by providing practical guidelines and instructions.
