Divination Principles
Divinate when in doubt; abstain when certain
Consult the oracle only when a genuine question or uncertainty weighs on your mind. Without doubt, do not cast casually.
One matter, one reading; do not repeat
Ask about the same matter only once. Repeated casts in quick succession can cloud the reading and diminish its clarity.
Wrong time, place, or reverence — do not cast
Avoid casting late at night, in the bedroom, or in impure settings. Wash your hands beforehand and settle body and mind.
Sincerity brings clarity; do not ask the unjust
Approach the oracle with a sincere, focused, and calm heart. Do not cast on matters that are improper or unreasonable.
Casting Method
Shi Yi simulates the traditional coin method: six tosses of three coins yield six lines, forming the hexagram. Changing lines are interpreted using Mr. Nan Huai-Chin's approach.
