Oracle Entities

In the highest abstraction level, an hexagram can be thought itself as a single entity in its own right; from a middle level, it can be thought as the combination of two trigrams; from the lowest, it is a combination of six lines. The six lines comprising the hexagram are ordered from bottom to top, thus the lower line of the hexagram is referred as the first line. The following oracle entities are associated to each hexagram:

1. The ``judgement'': It is the main idea that the hexagram encompasses itself.
2. The ``image'': It is the visual representation suggested by the spatial relationship between the two comprising trigrams.
3. The ``mutant lines particular judgement'': It is the main idea that each mutant line encompasses itself.
4. The judgement and the image of its mutant hexagram: The mutant hexagram is obtained by taking the opposite sense of the mutant lines present in the former hexagram. Fig. illustrates the idea: the left original hexagram is ``Wei Chi / Before Completion'' (No. 64), the right mutant one is ``P'i / Standstill'' (No. 12).
