妙法蓮華經文句 7.50

7.50

一云，大聖善巧，依四悉檀作如是說，或說佛道長遠，或說佛易得，對治厭道長者說短，於道生輕易想者說長，或為發生宿善，或隨世間所欲，或為聞說長短即得入第一義，當知言如許劫方今得羅漢者，此是權行四悉檀，引諸實行令入道耳。

One [explanation] states that the Great Sage is skillful: relying on the four siddhāntas he made such an exposition; sometimes he states that the Buddha Way is long and distant, and sometimes he states that buddhahood is easily attained; as a counteragent for those who are weary of the Way being long, he says it is short; for those who form the notion of the Way being easy and slight, he says it is long; or [it is] to bring forth past good roots, or in accordance with worldly desires, or so that hearing the explanation of length or shortness they might immediately enter the paramārtha-satya. One should know that stating they only now attain arhatship after such kalpas is an expedient practice of the four siddhāntas, guiding those of real practice to enter the Way.
