Visuddhimagga XVI-19

Catutthasaccaṃ pana yasmā etaṃ dukkhanirodhaṃ gacchati ārammaṇavasena tadabhimukhabhūtattā, paṭipadā ca hoti dukkhanirodhappattiyā. Tasmā dukkhanirodhagāminī paṭipadāti vuccati.

其次第四的道谛，因为是以苦之灭为所缘为目的而前进故得证于苦之灭，并且（此第四谛）是得至于苦灭之道，所以说为「导至苦灭之道」（dukkha-nirodha-gamini patipada）。

Ñ(XVI,19): [Nirodha-gāminī paṭipadā (way leading to cessation):] because the fourth truth goes (leads) to the cessation of suffering since it confronts that [cessation] as its object, and being the way to attain cessation of suffering, it is called dukkha-nirodha-gāminī paṭipadā, the way leading to the cessation of suffering.
