俱舍論疏 9.130

9.130

論「何緣中際至惑唯一故」，問廣、略也。何緣中際果開為五，惑分為二；後際果合為二，前際惑唯為一？

The Śāstra states: "For what reason are the middle limit... up to 'defilement is only one?'" This asks about the detailed and concise treatments: for what reason are the results of the middle limit expanded into five, while defilement is divided into two; and the results of the posterior limit are combined into two, while the defilement of the prior limit is only one?
