From which of the Natures does the ''Consuming Fire" come?

But, perhaps, this great confusion is a small thing to Mani ; and it is right that we should turn again and ask him of this Consuming Fire, from which of these Natures does its consuming nature come? If it is from the Darkness, how does it injure the body which is akin to its nature? And if it injures its nature, it would be right that it should injure itself also, if that nature which springs from it is injured. But if its harmfumess is from the Light, how could the Sons of the Darkness imprison it in their midst without being injured, seeing that bodies, their kinsmen, are not able to stand before its breath? And if they are two, as if from the two Natures of Good and Evil, then how did they receive [P. 104.] one another into union when they were opposed to one another? And all this (that he says, namely), 'they loved one another' is due to the fact that the difference between them is not known. And how did they become one mind, when they are both suspicious of the two Natures from which they have sprung? For when good and evil (persons) touch them (i.e., the Elements contained in Fire), they are both injured equally by both of them. And the good Fire which springs from the good Nature does not recognize the good, its kinsmen, just as also the evil Fire does not discern the evil, its [lxxxi] relatives. And in virtue of the test applied to this one Compound (i.e., Fire), we have a right to say that all that Mixture of the two Natures consists of one mingling of love. But if there are some of the Minglings which struggle with one another because they are opposed to one another, why does Fire not struggle with Fire?
