It lists all the main topics covered in the book, along with the page numbers where each subject can be found, and sometimes even a brief description of each topic... The index serves as a guide to the book, but it is not the book itself." Carefully, he closed the books in his hands and began placing them back on the shelves. "The same principle applies to the major law of any path— it contains the keys to all the Minor laws within that path, but it does not hold all their intricate details."
