2. During man's regeneration, the light of heaven, and at the same time the heat of heaven, is instilled into natural light; which two constitute, as it were, a new soul by means of which man is formed by the Lord. This light and heat are instilled through the higher mind, which is called the spiritual mind. By virtue of this instilling, or insertion, man becomes a new creature, and becomes more enlightened and more intelligent in the things of the Church, and in the reading of the Word; and this is the new understanding and the new will. By means of this light and this heat, man is afterwards led by the Lord and from natural becomes spiritual.
