If you're unsure of the purpose of the I Ching - get this book. If your understanding of the function of yang and yin is incomplete - read and contemplate on, hexagrams One and Two. Read one hexagram a day and the exercise produces a comprehensive view of the I Ching and its many uses, whether psychologically, strategically or spiritually. In fact, follow instructions. More importantly a practical and insightful understanding develops with regard to Personal Progression in one or all of these areas. Recommended to anyone whose Personal Development Program includes the development of others. Not just for Buddhists, as the title might suggest.
