Casting is the Tao's expression into the dimensional universe, as in "fragments cast from the Tao," and the order of it, as in "first-cast warrior in the entity." A person's casting is his position within his entity (see "Entity"), or commonly, just his primary cadence position (see "Cadence")

A permanent grouping of seven essences (souls). A primary cadence consists of seven essences of the same role; it is the smallest "building block" of the entity. An essence's numerical position within his cadence, and his cadence's position within his greater cadence, significantly influence how he directs his energies. (See also "Greater Cadences" and "Casting.")

Further, cadences are configurations of seven souls that, like entities and cadres, stay together for an entire grand cycles. They differ from temporary configurations (usually lasting several lifetimes) such as quadrates, sextants, triads, and so on that are formed, usually during the late baby and early young soul ages, for specific purposes relative to physical-plane tasks. A primary cadence is the smallest grouping of essences within an entity, and each member normally has the same role. There are many other kinds of cadences. We are part of more than one; occasionally, several.

Seven primary cadences join together into a greater cadence. So a greater cadence of servers, for example, consists of seven groups of seven servers, or forty-nine servers. Greater cadences also group together, although there can be any number of them—there doesn’t have to be seven, and there may be just one. Series of greater cadences of various roles make up the entity.
