Confucius' general comments come at the end of this introduction, but Confucius himself comments on specific hexagrams and lines, as you will find in the text. Commentaries on the I Ching have been written since King Wen and his son the Duke of Chou, purported authors of the original text, themselves wrote commentaries for it.
Many recent translations emphasize new-ageism, feminism, etc.
This version is a humanist translation. Since the whole universe of possibilities must be included in these 64 hexagrams, the oracle may be said to answer to any situation. The answers one finds in the I Ching give the relations between people, within a family, or in a state. Though quaint images may be used, the center of concern in the I Ching is always ethics and morality, the behavior of human beings. For this reason, Confucius greatly favored its use as a great humanist document.
