360. It shall now be told how love, when attacked, is enkindled and inflamed into zeal, as fire is enkindled into a flame. Love resides in man's will; but it is enkindled, not in the will, but in the understanding. In the will it is like fire, and in the understanding like a flame. In the will, love knows nothing about itself, for there it has no sensation of itself; nor does it there act of itself. Sensation and action are effected in the understanding and its thought. Therefore, when love is attacked, it rouses itself to anger in the understanding, this being done by means of various reasonings. These reasonings are like sticks of wood which the fire kindles and which then burn. Thus they are like so much fuel or so much combustible material from which comes the above-mentioned spiritual flame, of which there is much variety.
