A while back ago I started casting I Ching as part of my personal and guided study of Taoism. While I do not believe in divination in the convential Western understanding of such, I do subscribe to the theory advanced in Determinism...that being, "if one could observe all that has ever happened in the universe, one could predict all that would ever happen".
The point of casting I ching is not to "tell the future" but rather to get a deeper understanding of the present reality and possible outcomes by tapping our subconscious awareness.
The I Ching is supposedly the oldest transcript in existance. It means "Book of Changes". Although it can not be proven I Ching is the oldest book in the history of humanity, there is reasonable evidence that it antedates at least Homer and the Pentateuch. Respect for the I Ching has endured throughout its history: it was a pillar of Taoism; an inspiration for Chinese Ch'eng and Mahayana Buddhism; the I Ching is the ONLY book known to have been saved from the notorious "burning of the books" ordered by Emperor Shih Huang Ti some 2000 years ago; only the Bible, Koran, and Vedas can claim an influence on par with that of the I Ching.
In 1697, a French Jesuit missionary in China, Joachim Bouvet, introduced the I Ching to German mathematician and philosopher, Gottfried Wilhelm von Leibnitz, who was amazed by the Book of Changes and its use of binary arithmetic, then unknown in Europe. Leibnitz spread the good word, and thus our civilization was first introduced to binary arithmetic, which is not only the cornerstone of the Book of Changes but as most people know, the language of all modern computers. Leibnitz was not the only great mind fascinated with the I Ching. Foremost among those who extolled its merit was no doubt psychologist Carl C. Jung, who saw in the Book of Changes the most perfect illustration of his own Theory of Archetypes and referred to the I Ching as "the most profound book ever to come from the East."
Science and psychiatry have both worked to build bridges between the conscious and subconscious..this is one of the purposes of NLP for instance. As well as Biofeedback and Free Association Speech.
On a practical day to day level, I use I ching as a tool to help clarify a situation that I find confusing. I have been keeping records of my progress. Some of the "outcomes" and readings have been nothing less than incredibly accurate. I am not talking about "hocus pocus" fortune telling. Again, first and foremost the I Ching is a book of wisdom.
Does anyone else here have experience with I Ching?
