When is it appropriate to cast an I Ching hexagram?
Casting is most useful when the basic facts are known but a real dilemma remains about timing, relationships, or competing choices. It can help organize blind spots and action order, especially in questions such as “Under present conditions, what deserves attention?” or “What changes might follow this option?”
If the answer can be checked directly—such as a flight time, examination rule, medical test, or contract clause—check it or consult a qualified professional first. A casting should not replace evidence that is available.
