仁王護國般若波羅蜜多經疏 2.635

2.635

解曰：取著一二者，取相執著，見一定一、見二定二也。若有若無者，執俗定有、勝義定無，此皆妄情，世俗諦故。從此第五結非一二。

Commentary: "Grasping at one or two" means grasping at characteristics and clinging to them, seeing 'one' as definitely one and seeing 'two' as definitely two. "Whether existing or non-existing" means clinging to the conventional as definitely existing and paramārtha as definitely non-existing; all of these are deluded sentiments, because they are saṃvṛti-satya. Hereafter is the fifth part, concluding that it is neither one nor two.
