4.30

The explanation says: "Pervasive [only] of unwholesome minds" explains why shamelessness (āhrīkya) and lack of embarrassment (anapatrāpya) obtain the name "great unwholesome". That is, shamelessness and lack of embarrassment are, first, solely unwholesome by nature, and second, pervade all unwholesome minds; possessing these two characteristics, they alone obtain the name "great unwholesome". For example, though sensation and the like pervade unwholesome minds, they are not solely unwholesome by nature. Among the secondary defilements such as wrath, setting aside flattery (śāṭhya), deceit (māyā), and pride (mada), these seven as well as hatred (dveṣa), though solely unwholesome by nature, do not pervade unwholesome minds; hence they do not obtain the name "great unwholesome". The mental marks of these two will be explained later.
