How is symbolism used in this section of the book (Chapters 74-78), to tie up the symbols that were used throughout previous sections of the book?

This section of the book (Chapters 74-78) talks a great deal about the act that Sophie witnessed that severed her ties with her grandfather. The ceremony that Sophie's grandfather was involved in carried many symbols that are present throughout this book and are used as foreshadowing as well. The participants wore black or white; white for women, black for men. According to the author, these colors foreshadow the balance that Jacques seeks in his clues, such as the black cryptex within the white cryptex. The ceremony also represents the male and female aspects of divinity, which is a main theme in this book. The theme of incompleteness without the presence of male and female is also a symbol present in the ceremony and important to the author, as well, in choosing a male and female for the lead characters that are equally important in his story.
