Traditional Day Master reading

Geng: Firm Metal shaped into something useful

Geng’s traditional Metal is strong and responsive to shaping. The Day Master image can describe resolve, clear distinctions and a preference for meeting a problem directly. Refinement matters as much as force: the interpretive question is how determination becomes purposeful action. Fire and Water give the classical discussion different ways of describing that shaping and expression.
