Brief introduction to the content of Heluo Jingyun

The Essence of Heluo was written by Jiang Yong at the age of seventy-nine. The internal chapter "Heluo Essentials" consists of three volumes, which are derived from the four contents of Zhu's "Yi Xue Enlightenment". It says: "The origin of books, the principles of nature and nurture, the tactics of tactics and the method of changing careers are all contained in this chapter, which is the essence of Heluo." Volume one and volume two interpret Benjing and Original Gua Hua, and volume three interprets Ming Ji Ce and Kao Bian Zhan. There are six volumes in the external book "Yun of Heluo", taking the skill of Heluo Book as a reference: "A mathematician's five tones and six methods, an astronomer's seven know-how, a five-element family's Yin Na, a phonologist's letters are clear, Confucianism's Luo Qi Li, and the battle of choosing a day as the first special door, which makes the sky have five movements and six qi, and people have meridians and arteries, which is the foundation of medical treatment. He said: "Anyone who talks about the letter contained in the book and promotes other things can bypass this article because it is the moral of Heluo. ".Zhou Dunyi's Yi Tong said:" The essence of a saint is to draw hexagrams to show it; The sage means based on divination. " Jiang Yong was named after this book, and said in the preface: "The so-called elite naturally flows out, and there is no false intelligence arrangement; The so-called many a mickle makes a mickle, which is enough to make Yi Dao wonderful. More fundamentally, the essence of hexagrams is the essence of books, hexagrams have their right lines and books have their left vouchers. The meaning of books is the meaning of books, the descendants of books and the ancestors of books. "
