Tài Xuán Jīng

Tài Xuán Jīng (Tai Hsuan Ching; Chinese: 太玄經, "Canon of Supreme Mystery") is a divination system &mdash; similar to the more commonly known I Ching (Yì Jīng) system &mdash; based on a set of 81 tetragrams, composed by the Confucian writer Yáng Xióng (Yang Hsiung; Chinese: 揚雄/扬雄). It has been popularized to some extent in English as The Alternative I Ching.
