The Forest of Changes (Jiao Shi Yi Lin) is a Han Dynasty book of divination based on the Yi Jing. It expands the 64 hexagrams of the Yi Jing into 4096 verses, with one verse for each possible combination of two hexagrams. The work was created in the latter part of the Western Han or during the reign of Wang Mang. Much more than a diviners' tool, it contains numerous important insights into early Chinese culture, religion, history, myth and philosophy. This is the first translation of the entire work into a western language.
