成唯識論演祕 5.34

5.34

如三受門，苦、樂二受含憂、喜故，而言根者即不如是，二十二根喜、樂、憂、苦各別立故，故寬狹異。

As in the section on the three sensations, the two sensations of pain and pleasure contain sorrow and joy; but speaking of the faculties, it is not like this, because among the twenty-two faculties, joy, pleasure, sorrow, and pain are each established separately; therefore, the broad and narrow differ.
