2. During man's regeneration, the light of heaven is instilled into natural light, and at the same time the heat of heaven; these two constitute, as it were, the new soul, through 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 matters of the church, and consequently in the reading of the Word. This also is the new understanding and the new will. Afterwards the man is led by the Lord through the above light and through the above heat, and from natural becomes spiritual.
