for the left-brained, one of Robert Breedlove's definitions is my favorite: "attention-allocation technology;" i take it a step further - "allegiance tokens:" makes one think who is the master of money; ultimately, it's the "one-mind" or "mind's one eye (mono-eye)" - the money is in the mind; the closer one can get with the idea of "money" to the "one-mind" the more sovereignty (knowledge of the self) or archony (master-slave relationship);
