俱舍論疏 23.59

23.59

論「然於增進至不修彼行相」，明中上忍隨所減緣不修彼行。《正理》釋云「謂具緣四，具修十六。若緣三、二、一，如次修十二、八、四。」

The treatise says: "However, in the increase and advance ... one does not cultivate those aspects." This clarifies that in the middle and highest acceptance, according to whatever objective condition is eliminated, one does not cultivate those aspects. The Nyāyānusāra explains: "That is to say, when fully taking the four [truths] as condition, one fully cultivates the sixteen [aspects]. If one takes three, two, or one as condition, one cultivates twelve, eight, or four, respectively."
