Blofeld compiled this 1963 translation of the Book of Changes (Yi Jing) intending to present primarily the divinatory aspects of the I Ching in the notes and explanatory chapters. In his efforts he had the assistance of several learned native Chinese I Ching scholars. As useful as it is informative, the book includes not only the text and commentaries for all 64 hexagrams (with changing lines), but as well the background of the Book of Change, its symbolical basis, method of divination and guide to interpretation; and a variety of tables and diagrams for assisting interpretation.
