「如是已說至不善心有」者，此下第四明大不善地法。就中，一釋名、二辨體，此即釋名。兩重依主釋，亦準前釋。恒遍不善，故名為大。

On "Such has been explained ... exist in unwholesome minds": Hereafter is the fourth section, clarifying the factors of the ground of great unwholesomeness (mahākuśalabhūmika). Within this: first, explaining the name; second, identifying the substance. This [passage] explains the name. The two-tiered determinative compound (tatpuruṣa) is also explained in accordance with the preceding. Because they are constantly universal to the unwholesome, they are called 'great.'
