I Ching divination (suan gua) uses hexagram casting to reflect a situation and its likely change— for decision support, not fixed fate.
Methods
- Three-coin casting (most common)
- Yarrow stalk (classical)
- Time/number methods → Plum Blossom
- Advanced: Liu Yao with six relations
Ethics
One question per session; avoid repeated casting until you like the answer; use results as reference alongside rational judgment.
