The nature of the I Ching is transformation. Each element pairs in succession with another in an interaction. Sometimes, the forces of Yin and Yang alter the elements and they transform. It is in these transformations that the I Ching becomes known as The Book of Changes.
On our journeys of self-mastery and balance through all of life's moment-to-moment and day-to-day changes, through every turn of the seasons, the I Ching describes the movements of the energies around us which can be useful in everyday life and practical in bringing our spiritual and mental/emotional development down-to-earth in our everyday lives.
The I-Ching addresses the handling of our internal and external aspects of light and dark. When particularly handling our Shadow-side, our limiting beliefs, and our internal struggles or anxieties, I am drawn to Hexagram/Passage #6, "Conflict", which describes the reflection of internal conflicts on our external experiences and perceptions. Also, Hexagram/Passage #18, "Decay", which describes the best route to handling limiting beliefs, bad habits, and other self-sabotaging tactics we use to hold ourselves in a complacent blanket of false security. These are just two out of 64 passages which address embracing goodness, learning self-mastery, and releasing the mental/emotional entrapment of our Shadow-side. It is not a practice in denial but the dynamic fullness of mindful acceptance.
My recommendations for a copy/translation/interpretation of The I-Ching, or The Book of Changes, are from the following authors: Brian Brown Walker (1993), Carol K. Anthony (1980), or Wilhelm & Wilhelm (1950). There are numerous translations, apps, and digital copies available, though I have so far appreciated these three the most. What you can conveniently find for yourself, The I-Ching is an invaluable piece of thoughtful, accessible, and practical guidance necessary to any spiritual library.
