867. And the books were opened; and another book was opened, which is the book of life, signifies that the interiors of the minds of them all were laid open, and by the influx of light and heat from heaven their quality was seen and perceived, as to the affections which are of the love or will, and thence as to the thoughts which are of faith or of the understanding, as well the evil as the good. By "books" are not meant books, but the interiors of the minds of those who are judged, by "the books," the interiors of the minds of those who are evil, and are judged to death, and by "the book of life" such as are good, and are judged to life. They are called "books," because in the interiors of the mind of everyone are inscribed all the things that he thought, intended, spoke, and did in the world from the will or the love, and thence from the understanding or faith; all these things are inscribed on the life of everyone, with so much exactness that not one of them is wanting. The quality of all these things appears to the life, when spiritual light, which is wisdom from the Lord, and spiritual heat, which is love from the Lord, flow in through heaven. Spiritual light discloses the thoughts which are of the understanding and faith, and spiritual heat discloses the affections which are of the will and love; and spiritual light together with spiritual heat disclose the intentions and endeavors. That this is the case, I do not say that the rational man can see from the light of his own understanding; but he can if he will, provided he be willing to understand that there is given spiritual light which enlightens the understanding, and spiritual heat which enkindles the will.
