21 Biting Through Ruling, Problem Solving In a context of enlightenment, a new beginning, we utilise setting a direction (an ideology). "SHIH HO - SHIH : bit away, chew; bite persistently and remove; snap at, nibble; reach the essential by removing the unnecessary. The ideogram: mouth and divination, revealing the essential.. HO : close the jaws, bite through, crush between teeth. The ideogram: mouth and conver, jaws fit together as a lid fits a vessel." ERANOS p276

In hexagram 21the focus is on methodology in dealing with problems, finding solutions to things, and in so doing define a sense of direction through revelation of the essential. This is equivalent to identifying the 'plot' of some story and so we treat each hexagram as a story and through XOR-ing the hexagram with 21, reveal its 'plot'. This is associated with the such other XOR-generated material as finding a hexagram's 'infrastructure' (27-ness) or it source of nourishment (48-ness)
