23.22

第四解一趣應知，由三種相道名一趣，謂於異生地，以五行相，觀察諸行。則此諸行，於二時中，修治令淨，謂於行向學地及無學地，足前異生為三相也。云何名五行下，別出五行？達師云：言五處者，五蘊處也。言自性者，但是苦諦所攝，有漏諸行自性。言諸行因緣者，集諦所攝能感苦諦因緣也。雜染因緣者，喜受也。清淨因緣者，過患也。清淨者，所得滅諦也。

Fourth, in explaining 'one destination' (ekāyana), it should be known that the path is called 'one destination' by virtue of three kinds of characteristics: namely, on the stage of ordinary beings, one observes formations through five aspects; then one cultivates and purifies these formations across two stages—namely, on the stage of those in training who are progressing [on the path] and on the stage of those beyond training; together with the preceding ordinary beings, these make three characteristics. As for the passage below, 'What are the five aspects?', which specifies the five aspects: Master Da says: 'The phrase "five bases" refers to the bases of the five aggregates. The phrase "own-nature" refers only to the own-nature of conditioned, tainted formations subsumed under the truth of suffering. The phrase "causes and conditions of formations" refers to the causes and conditions subsumed under the truth of arising that can bring about the truth of suffering. The "cause and condition of defilement" is pleasant feeling. The "cause and condition of purification" is peril. "Purification" is the acquired truth of cessation.'
