「不說心狂至不染污心」者，答。謂惡業因感不平等異熟大種，依此大種勢力，心便失念，故說為狂。體非異熟，善、惡心等皆容狂故。故《正理》云「由此心狂體非異熟，善惡心等皆容狂故（已上論文）。」如是心狂對於心亂，應作四句。第一句狂非亂者，謂狂者不染污心，失念故名狂，不染污故名非亂。第二句亂非狂者，謂不狂者諸染污心，染污故名亂，不失念故非狂。第三句狂亦亂，謂狂者諸染污心，失念故名狂，染污故名亂。第四句非狂亂者，謂不狂者不染污心，不失念故非狂，不染污故非亂。應知此中染名為亂，失念名狂。

"It is not said that mental madness... non-defiled mind": Answer. That is, the cause of bad karma brings about disproportionate ripening great elements; based on the force of these great elements, the mind loses mindfulness, and therefore it is called madness. Its intrinsic nature is not ripening, because wholesome and unwholesome minds alike are capable of madness. Thus the *Nyāyānusāra* says: "Because of this, the intrinsic nature of mental madness is not ripening, for wholesome and unwholesome minds alike are capable of madness (end of treatise passage)." Thus, when mental madness is contrasted with mental distraction, a fourfold proposition should be made. The first alternative, mad but not distracted: refers to a mad person's non-defiled mind; because of losing mindfulness it is called mad, but because it is non-defiled it is called not distracted. The second alternative, distracted but not mad: refers to a non-mad person's defiled minds; because they are defiled they are called distracted, but because they do not lose mindfulness they are not mad. The third alternative, both mad and distracted: refers to a mad person's defiled minds; because of losing mindfulness they are called mad, and because they are defiled they are called distracted. The fourth alternative, neither mad nor distracted: refers to a non-mad person's non-defiled mind; because of not losing mindfulness it is not mad, and because it is non-defiled it is not distracted. It should be understood that here, defilement is called distraction, and loss of mindfulness is called madness.
