4.46

釋曰：初定除不善及惡作睡眠者，謂初靜慮，如前欲界諸心所法，唯除不善。不善有十，謂瞋一，小煩惱中忿等七，除諂、誑、憍，及無慚、愧，此十煩惱唯不善性，色界無有。除惡作者，惡作與憂根相應，色界離憂，故無惡作。除睡眠者，色界無段食，故無睡眠也。

The commentary explains: Regarding "The first absorption excludes the unwholesome, as well as remorse and torpor": in the first absorption, like the mental factors of the desire realm described above, only the unwholesome is excluded. The unwholesome comprise ten: hatred as one, seven among the minor defilements—wrath and the like, excluding deceit, dissimulation, and complacency—and the absence of shame and conscience. These ten defilements are purely unwholesome by nature, and do not exist in the form realm. Remorse is excluded because remorse is associated with the faculty of grief, and the form realm is detached from grief, hence remorse is absent. Torpor is excluded because in the form realm there is no material food, hence no torpor.
