Among 64 stories of I-Ching, the most important stories are #01: Creative and #02 Receptive.
Story #01 Creative is about the story of a dragon.
Story #02 Receptive is a story of a female horse.
Those are the metaphor for yin and yang.
My I-Ching mentor, who studied I-Ching for over 50 years, always says" If you deeply understand the first two stories in depth.
The remaining 62 stories are easy to use."
