4.30

釋曰：此遍不善心者，釋無慚、無愧，得大不善名也。謂無慚、無愧，一則唯不善性、二則遍一切不善心，具此兩義，獨得大不善名。且如受等雖是遍不善心，不是唯不善性。忿等七惑，除諂、誑、憍，此七及瞋雖唯不善性，不是遍不善心故，皆不得大不善名。此二行相，如後當釋。

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.
