成唯識論述記 5.787

5.787

述曰：此中不善，翻善可知，惡趣苦果，今解彼文，准前亦爾。但是無記苦果，令身苦故。

The Commentary states: Here, "unwholesome" can be understood by reversing "wholesome." The painful fruit of the wretched destinies, when explaining that text now, should be deduced as also being like the former: it is merely indeterminate painful fruit, because it causes the body to suffer.
