312. The nature of man's internal, unless it is reformed by the Lord, has been made evident to me from seeing the devils and satans in hell; for they have it constantly in mind to kill the Lord; and as they cannot do this they are in the endeavor to kill those who are devoted to the Lord; but not being able, as men are in the world, to do this, they make every effort to destroy their souls, that is, to destroy faith and charity in them. With such, essential hatred and revenge appear like lurid and glowing fires-hatred like a lurid fire, and revenge like a glowing fire-yet these are not fires, but appearances. The cruelties of their hearts sometimes appear above them in the air like contests with angels and their slaughter and overthrow. Such direful mockeries arise from their wrath and hatred against heaven. Moreover, at a distance, these same spirits appear like wild beasts of every kind, as tigers, leopards, wolves, foxes, dogs, crocodiles, and all kinds of serpents; and when they see gentle animals in representative forms, they rush upon them in fantasy and strive to tear them in pieces. They came to my sight like dragons standing near women with whom there were little children, whom they were endeavoring, as it were, to devour (according to what is recorded in the twelfth chapter of Revelation); but these were nothing else than representations of hatred against the Lord and His New Church. That men in the world who wish to destroy the Lord's church are like these spirits is not evident to their companions; and for the reason that their bodies, through which they practice the moralities, absorb and conceal these things. But to the angels, who behold their spirits and not their bodies, they appear in forms like those of the devils above described. Who could have known such things had not the Lord opened the sight of some one, and given him the ability to look into the spiritual world? Otherwise, would not these, together with other most important matters, have lain concealed from man for ever?
