俱舍論記 2.6

2.6

「如是已說至所緣異故」者，頌本唯明障礙，長行義便明三有對。對是礙義，礙有二種：一障礙、二拘礙。若障礙有對，是障礙礙。若境界、所緣有對，是拘礙礙。此即標章。

"It has thus been explained ... because their cognitive objects are distinct" means: the root verse only clarified obstructive resistance (pratigha), but the prose conveniently clarifies three kinds of resistance (sapratigha). "Resistance" (pratigha) means obstruction; obstruction is of two kinds: first, obstructive resistance (āvaraṇa-pratighāta); second, restrictive resistance (bandhana-pratighāta). Obstructive resistance is the obstruction of hindrance. Cognitive-field resistance (viṣaya-pratighāta) and objective-support resistance (ālambana-pratighāta) are the obstruction of restriction. This then marks the headings.
