因明入正理論疏 2.174

2.174

述曰：此顯異分。并前合顯俱一分轉。彼二宗中，皆說覺、樂、欲、瞋等為心、心所，此二非常，為常異品。無質礙因於樂等中有、於瓶等上無，故是異分。

Commentary: This reveals its occurrence in a part of the heterologue. Combined with the preceding, it reveals occurrence in a part of both classes. In those two traditions, awareness, pleasure, desire, aversion, and so forth are all stated to be mind and mental factors; these two are not permanent and are the heterologues of permanence. The reason "lacking tangible obstruction" is present in pleasure and the like and absent in jars and the like, so it occurs in a part of the heterologue.
