『正易』 ‘九九吟’의 易哲學的 의미

Abstract

This paper aims to explore the philosophical meaning, through I-ching(『易經』), of the three-part of Gugueum(九九吟) in Jeongyeok(『正易』) which contains the core principle of jeongyeok(正曆), 360 days, Hetu(河圖) and Luoshu(洛書) within. First, in Chapter 2, the academic process and study techniques, such as Yeonggamudo(詠歌舞蹈) and Sujisangsu(手指象數), were discussed through reading and learning I-ching(『易經』) and self-cultivation. This is something unique to Jeongyeok that makes traditional academic methods be inherited. In Chapter 3, the 360 ​​days and the numerology of Hetu and Luoshu are examined. The principle of the use of the 360-day calendar and Hetu and Luoshu, revealed through the number of Daeilwon(大一元), 300, and the number of Mumuwi(无无位), 60, which clearly demonstrate the Jeongyeok studies. In Chapter 4, the academic practice of ‘Making one's will sincere(誠意),’ Correcting one's thought(正心)’ and Jongsimutae(終始无怠) is discussed. It is necessary to correct the nature of one's heart through ‘Making one's will sincere’ and ‘Correcting one's thought,’ which are the eight major items of The Great Learning(『大學』), and to realize and practice the principle of Jongsi(終始), the movement of heaven, represented by the final formation of Juyeok(『周易』). Jeongyeok(『正易』) is not a different study from Juyeok(『周易』), but rather reveals the truth hidden or not revealed in Juyeok. The academic content of Jeongyeok can be organized into Jeongyeok's eight trigram, Hetu and Luoshu, and the 360-day calendar, all based on Juyeok. First of all, it is Jeongyeok's eight trigram, which is the source of writing Jeongyeok. In 「Daeyeokseo」, Confucius emphasized that he only drew the principles already revealed. The second is ‘Hetu and Luoshu,’ which discusses the principles of number. As considered in the main text, it is based on what was revealed through repairs from 1 to 10 in Juyeok’s the first volume Xici, Chapter 9. The third is the four calendars of 375, 366, 365 4/1, and 360, which are also based on the 360 ​​days revealed in the first volume of Xici, Chapter 9.
