The I CHING, or "Book of Changes" was compiled, on the basis of much older material, by King Wen, who ruled China in the twelfth century B.C. and his son, the Duke of Chou, as well as commentaries attributed to Confucious and his disciples. The oracle book is based upon the spiritual philosophy that by correct action, men and women are capable of making their own destiny. By making proper responses to particular circumstances and events, one can cease being blown hither and thither by the winds of fate and use one's own strength to decide what the future holds.
