As all things in creation relate to good and truth (see Part 1), so all things in a person relate to the will and the understanding. These two halves of the human mind are both the receivers of good and truth and the place where good and truth act on a person—good with the will and truth with the understanding. Together, will and understanding make the whole life of a person. Everything that was said about good and truth in part 1, can also be said about will and understanding, since these two faculties are where good and truth reside in a person. In the heavenly marriage, the will is the essence or substance of a person’s life and understanding is the expression or form of that life. Good in the will causes truth to form the understanding, and the will takes its quality from the form of the understanding. Finally, since the life of a person is essentially in the will, the quality of a person’s life is based wholly on fitting your life into the shape of genuine truth.
