俱舍論頌疏論本 2.22

2.22

釋曰：上兩句釋難，下兩句出體。傳說分別，略有三種：一自性分別、二計度分別、三隨念分別，由五識身雖有自性而無餘二。論云：「如一足馬名為無足，是故經中說無分別。」自性分別者，體唯是尋，後心所中自當辨釋。

Commentary: The first two lines resolve the objection; the latter two lines identify the essential nature. Tradition states that conceptualization is broadly of three kinds: 1. conceptualization of intrinsic nature (svabhāva-vikalpa), 2. deliberative conceptualization (abhinirūpaṇā-vikalpa), and 3. recollective conceptualization (anusmaraṇa-vikalpa). Because the five consciousness-bodies, although possessing intrinsic nature [conceptualization], lack the other two, the śāstra says: "Just as a one-legged horse is called legless, so the sūtras say that they are without conceptualization." As for conceptualization of intrinsic nature, its essential nature is vitarka alone, which will be explained below among the mental factors.
