妙法蓮華經玄義 4.197

4.197

無量四諦，凡有四種：有無量四諦，不伏破塵沙，亦不伏破無明；有無量四諦，傍伏破塵沙，不伏破無明；有無量四諦，正伏破塵沙，亦伏無明；有無量四諦，正伏破塵沙，亦伏破無明。云何無量不伏破塵沙，不伏破無明？若三藏伏道有十六諦觀，明障真之惑有無量種，此乃伏於見思，何關塵沙？例如外道分別世智，非伏見思。云何無量是傍伏破？若通教七地出假，分別藥病，此助滅界內，非正伏破。云何無量正伏破塵沙？此是別教分別內外四諦，有無量種，即是伏破塵沙，亦伏無明，乃有破無明義。今從事得名；伏無明者，為便也。云何無量伏破無明？若圓教三諦，俱照法界事、理，無不明了，破自地無明，伏上地無明。

As for the immeasurable four truths, in general there are four kinds: there are immeasurable four truths that neither suppress nor destroy dust-and-sand [delusions], nor suppress nor destroy ignorance; there are immeasurable four truths that incidentally suppress and destroy dust-and-sand, but do not suppress ignorance; there are immeasurable four truths that properly suppress and destroy dust-and-sand and also suppress ignorance; and there are immeasurable four truths that properly suppress and destroy dust-and-sand and also suppress and destroy ignorance. Why do the 'immeasurable' not suppress or destroy dust-and-sand, nor suppress or destroy ignorance? In the suppression path of the tripiṭaka [teaching], there are sixteen contemplations of the truths; while it clarifies that the delusions obstructing truth are of immeasurable kinds, this merely suppresses [the delusions of] views and thoughts—what has it to do with dust-and-sand? This is just as non-Buddhists distinguish worldly wisdom, which does not suppress views and thoughts. Why are the 'immeasurable' an incidental suppressing and destroying? If it refers to the seventh stage of the shared teaching stepping into the provisional and distinguishing medicines and sicknesses, this merely assists in extinguishing [delusions] within the realms, and is not a proper suppressing and destroying. Why do the 'immeasurable' properly suppress and destroy dust-and-sand? This is the distinctive teaching's differentiation of the internal and external four truths into immeasurable kinds; this is precisely suppressing and destroying dust-and-sand and also suppressing ignorance, and indeed possesses the meaning of destroying ignorance. Here it derives its name from phenomenal practice; to speak of 'suppressing ignorance' is for convenience. Why do the 'immeasurable' suppress and destroy ignorance? In the three truths of the perfect teaching, both the phenomena and principle of the dharma realm are illuminated without any lack of clarity, destroying the ignorance of one's own stage and suppressing the ignorance of the higher stages.
