大方廣佛華嚴經疏 13.14

13.14

四解妨難。問既彰佛語業。答說法。問：佛所說法多門。何以唯陳四諦？答：以名雖在小，義通大小事理具足。謂苦集二諦是世間因果，所知所斷無改易故；滅道二諦出世間因果，所證所修事決定故。知斷證修，能運眾生到彼岸故。世界有異，此獨無改。況無量無作，何義不收。是故約此以顯差別。又為破計引機故，謂演彼聲聞四諦局法令亡所執，引入一乘無邊諦海，故約此辨。何以四諦皆帶苦言？謂苦滅聖諦等。然謂生苦之集，故云苦集；盡苦之滅，名為苦滅；至苦滅之道，名苦滅道。不得單言苦道，以道非生苦，不同集故。又非滅苦，不同滅故。能證苦滅，故云苦滅道。

Fourth, resolving difficulties. Question: Since the Buddha's verbal action has been revealed to answer [the question on] preaching the Dharma, question: The Dharma preached by the Buddha has many gateways; why only set forth the four truths? Answer: Although the names belong to the Small [Vehicle], their meaning extends to both Great and Small, completely possessing phenomena and noumenon. Namely, the two truths of suffering and origination are mundane cause and effect, being what is known and what is severed without alteration; the two truths of cessation and path are supramundane cause and effect, being what is realized and what is cultivated with definitive phenomena. Knowing, severing, realizing, and cultivating can transport sentient beings to the other shore. Although worlds differ, this alone does not change. How much more so with the limitless and the unconditioned—what meaning is not gathered in them? For this reason, these are used to reveal differences. Furthermore, to shatter attachments and guide capacities—meaning to expound those four truths of the śrāvakas to cause them to abandon what they cling to and guide them into the boundless ocean of truths of the Ekayāna—they are analyzed according to this. Why do all four truths carry the word "suffering"—namely, the "noble truth of the cessation of suffering", and so forth? Because it is the origination that produces suffering, it is called the "origination of suffering"; the cessation that exhausts suffering is called the "cessation of suffering"; the path that leads to the cessation of suffering is called the "path of the cessation of suffering". One cannot simply say the "path of suffering", because the path does not produce suffering, unlike origination; nor does it extinguish suffering, unlike cessation. Since it can realize the cessation of suffering, it is called the "path of the cessation of suffering".
