瑜伽師地論略纂 1.57

1.57

狂有五緣。《俱舍》第十五以妄念為體。彼論云：依不平等大種故，心便失念，故以妄念為體，或俱時心、心所為性。以狂對亂為四句：狂非亂，狂者不染心；亂非狂，不狂者染心；俱句，狂者染心；俱非句，不狂者不染心。此唯欲界，除北洲，五趣皆有。北洲人無逼惱，諸天有故。小乘佛有，大乘不然，十地亦無。

Madness has five conditions. The fifteenth fascicle of the Kośa takes forgetfulness as its essence. That treatise says: Due to a disharmony of the great elements, the mind loses mindfulness, hence it takes forgetfulness as its essence, or it takes the concomitant mind and mental factors as its nature. Comparing madness with distraction yields four alternatives: (1) Mad but not distracted: a mad person's undefiled mind; (2) Distracted but not mad: a non-mad person's defiled mind; (3) Both: a mad person's defiled mind; (4) Neither: a non-mad person's undefiled mind. This occurs only in the desire realm; except for the Northern Continent (Uttarakuru), all five destinies have it. Beings of the Northern Continent have no torment, while the gods do have it. In the Hīnayāna, the Buddha may have it; in the Mahāyāna, it is not so, and it is also absent on the ten bhūmis.
