The I Ching , or Book of Changes , is one of the the oldest books of humanity. Each of the 64 cards in this unique deck expresses an archetypical truth. Following the Book of Changes , every card can turn into another, with Yin solidifying into Yang, and Yang melting into Yin. Includes text by I Ching expert Lunaea Weatherstone. The companion booklets for most Lo Scarabeo decks are in five languages: English, Spanish, French, Italian, and German.
