845. The reason why the “fountains of the deep” signify temptation as to what is of the will, and the “cataracts of heaven” temptation as to what is of the understanding, is that it is what is of the will of man that is influenced by hell, and not so much what is of the understanding, unless this has been immersed in cupidities, which are of the will. Evils, which are of the will, are what condemn man and thrust him down to hell, and not so much falsities, unless they become conjoined with evils, for then the one follows the other. The truth of this statement may be seen from the case of very many of those who are in falsities, and are yet saved, which is the case with many among the Gentiles, who have lived in natural charity and in mercy, and with Christians who have believed in simplicity of heart. Their ignorance and simplicity excuse them, because in these there can be innocence. But it is otherwise with those who have confirmed themselves in falsities, and have thus contracted such a life of falsity that they refuse and reject all truth; for this life of falsity must be vastated before anything of truth and thus of good can be inseminated. It is, however, still worse with those who have confirmed themselves in falsities under the influence of their cupidities, so that the falsities and the cupidities have come to constitute one life; for these are they who plunge themselves into hell. This is the reason why temptation as to what is of the will is signified by the “fountains of the deep” which are the hells, and temptation as to what is of the understanding by the “cataracts of heaven” which are the clouds, from which comes rain.
