IChing Diviner is a divination and philosophical tool. IChing Diviner features a line-by-line interpretation of the 64 hexagrams (six-line drawings) from the highly regarded IChing (Book of Changes). Lines progress from the bottom to the top of the hexagram, and when they change, having either a circle or a cross on them, they become opposites. For example, a Yang line becomes a Yin line. Thus, when you caste the IChing and the resulting six-line hexagram contains changing lines, another hexagram is produced containing the static lines from the first hexagram as well as the newly-formed changed lines. In divination terms, the first hexagram represents the present, while the second hexagram represents the future.
