Traditional Day Master reading

Yi: Branches, flowers and a climbing vine

Yi brings the image of supple growth that reaches its destination through small adjustments. A Day Master reading can explore adaptability, responsiveness and the ability to work with surrounding conditions. The vine’s connection to a larger tree also gives this image a relational quality: support can extend its reach, while excessive accommodation can obscure its own direction.
