I Ching questions, answered
Can you ask the I Ching the same question twice?
Traditionally, no: the first cast is the answer and repeating it muddies the reply. When asking again is legitimate, and what to do instead of recasting.

Ask about one matter, frame it around your own conduct, and prefer open questions. Ten before-and-after examples of questions the I Ching can answer.

Cast when a real question arises, not to calm a worry. The tradition's case for rare consultation, the case for daily study, signs of over-casting, and a routine.

Traditionally the inscribed side (字) counts 2, yin, and the plain side (背) counts 3, yang. Why, what modern books do, and why consistency matters most.
Read →What coins should you use for the I Ching?
Any three coins work. Chinese cash coins are traditional, but what matters is a fixed rule for which side counts 3, and a calm, sincere approach.
Read →Casting the I Ching for someone else: who tosses, how to ask, how to tell them
You can cast for a friend or client; diviners have done so since the Zhou. Let them own the question, agree who tosses, and present the text, not a verdict.
