Introduction

Under the Introduction menu are pages describing fundamental concepts of the I Ching such as yin and yang, the gua/yao structure of the book’s essential imagery and practice methods.

The first page refers to Shao Yong, 1012-1077, a Song Dynasty philosopher, poet and historian, and a contribution he made to I Ching study known as Fu Xi’s arrangement of the gua, that happened to attract the mathematical interest of Gottfried Leibniz 600 years later.

The second page is an introduction to yin and yang, a complementary natural duality at the foundation of the I Ching and traditional Chinese philosophy.

Additional introduction pages are available for members, including a page about the structure of the 64  images (gua) composed of various mixtures of six yin and yang lines (yao), each being the subject of a chapter of the I Ching; a page describing how random selection of gua serves purposes such as contemplation and divination; and a page with some miscellaneous notes about the I Ching.
