詳曰：按教准理，諸無為法亦有得得，故《雜集論》第五云：謂於善、不善、無記法，若增若減假立得、獲、成就，既云於善而立得等，無為何無？文不遮故，言增減者即得、非得，證得名增，不得名減。

Detailed analysis: According to the teaching and conforming to reason, unconditioned dharmas also have acquisition of acquisition. Thus fascicle 5 of the Abhidharmasamuccaya-bhāṣya says: 'That is to say, upon wholesome, unwholesome, and neutral dharmas, according to increase or decrease, acquisition, attainment, and possession are provisionally established.' Since it says that acquisition and so forth are established upon wholesome [dharmas], why should the unconditioned lack them? The text does not exclude it. What is called 'increase or decrease' refers to acquisition and non-acquisition: realizing acquisition is called increase, and non-acquisition is called decrease.
