3224. It is surprising that man does not as yet know that his intellectual mind is in a certain light that is altogether different from the light of the world; but such is the condition that to those who are in the light of the world the light of heaven is as it were darkness, and to those who are in the light of heaven the light of the world is as it were darkness. This arises principally from the loves, which are the heats of the light. They who are in the loves of self and of the world, thus only in the heat of the light of the world, are affected solely by evils and falsities, and these are the things which extinguish truths, which are of the light of heaven. But they who are in love to the Lord and in love toward the neighbor, thus in spiritual heat, which is of the light of heaven, are affected with goods and truths, which extinguish falsities; but still with these persons there exists a correspondence.
 Spirits who are only in the things which are of the light of the world, and are thence in falsities derived from evils, have indeed light from heaven in the other life, but such a light as is fatuous, or as that which issues from a lighted coal or firebrand; but on the approach of the light of heaven this light is at once extinguished, and becomes thick darkness. They who are in this light are in phantasies, and the things which they see in phantasies they believe to be truths, nor to them is anything else truth. Their phantasies are also closely bound to filthy and obscene objects, with which they are most especially delighted; thus they think like persons who are insane and delirious. In regard to falsities, they do not reason whether these be so or not, but they instantly affirm them; whereas in regard to goods and truths they carry on a continual ratiocination, which terminates in what is negative.
 For truths and goods, which are from the light of heaven, flow into the interior mind, which with them is closed; wherefore the light flows in around and outside of this mind, and becomes such that it is modified solely by the falsities which appear to them as truths. Truths and goods cannot be acknowledged, except with those whose interior mind is open, into which the light from the Lord may inflow; and so far as this mind is open, truths and goods are acknowledged. This mind is open only with those who are in innocence, in love to the Lord, and in charity toward their neighbor; but not with those who are in the truths of faith, unless they are at the same time in the good of life.
