1. The zeal of a good love is like a heavenly flame, which never leaps out to attack another, but only defends itself - defending itself against an evil assailant in much the same way as when such a one rushes at fire and is burned; whereas the zeal of an evil love is like a hellish flame, which spontaneously leaps out and rushes upon another and tries to devour him. 2. The zeal of a good love immediately dies down and softens when the other desists from the attack; whereas the zeal of an evil love persists and is not extinguished. 3. The reason for this is that the internal element in one who is prompted by a love of good, is, in itself, gentle, mild, friendly and kind. Consequently, even when, to protect itself, the external element hardens, stiffens, bristles, and so acts harshly, still it is tempered by the goodness which moves its internal element. Not so in evil people. In them the internal element is hostile, savage, harsh, seething with hatred and vengeance, and it feeds on the delights of those emotions. And even if it is appeased, still those emotions lie concealed within, like fires smoldering in the wood beneath the ash; and if these fires do not break out in the world, nevertheless they do after death.
