There are so many books on the I Ching and how to interpret the hexagrams it's unreal. This volume is more of a general interpretation as opposed to another one that I own that is geared towards love/relationships.
I'm no expert on the subject, but the few readings I've done for myself have been scary accurate. When your Oracle speaks to you, you should listen.
Ok... to the point. This comes with three coins. I've never used yarrow sticks before so I can't really compare. I learned with coins, so that's what I'm comfortable with.
The pages of the book are split in half horizontally so that you can flip back and forth to match up the two trigrams that make the hexagram. This makes the experience incredibly easy. No flipping from one section of the book to another. Cast your first trigram and turn to it on the bottom section of the book, then cast the top and turn to the corresponding page a the top and voila! Interpret away!
The translator/authors interpretations of each trigram is very well written. It's written for you and me, not some scholar working over old scrolls in some musty old candle lit dungeon. The instructions at the beginning of the book are very good at getting you started with this endeavor. It's a great stepping stone if you want to gain a greater understanding of the I Ching or if you just want to be amazed and content with using this as your Oracle.
