妙法蓮華經玄義 6.122

6.122

二者直就顯露漸教中更明四教者，即是三藏、通、別、圓也。三藏教直對三法界，別說或九、或十一。通教對四法界，通說十二部法也。別教對兩法界，通說十二部法。圓教對一法界，通說十二部法。前以無記化化禪，與諸慈悲合，示現身輪：或為國師、道士、儒林之宗，父母、兄弟，乃至猴猨鹿馬，同事利益不可稱說。今口輪說者，例如前用諸慈悲，熏無記化化禪，種種不同，百千萬法不可說。不可說故，龍宮象負，渧海研山，八萬四千法藏，不可窮盡。雖復無崖，以十二部往收，罄無不盡也。

Second, directly taking the gradual teaching among the manifest to further explain the four teachings: these are the tripiṭaka, shared, distinctive, and perfect teachings. The tripiṭaka teaching directly addresses three dharma realms, specifically explaining either nine or eleven [genres]. The shared teaching addresses four dharma realms, universally explaining the twelve genres of teachings. The distinctive teaching addresses two dharma realms, universally explaining the twelve genres of teachings. The perfect teaching addresses one dharma realm, universally explaining the twelve genres of teachings. Previously, [it was explained that] using morally neutral transforming dhyāna in conjunction with various forms of compassion, [the Buddha] manifests the wheel of the body: appearing as a national preceptor, a Daoist master, the leader of Confucian scholars, a parent, a sibling, or even a monkey, deer, or horse, benefiting them through shared activities beyond description. Now, regarding what is expounded by the wheel of the mouth, it is like the previous use of various forms of compassion perfuming the morally neutral transforming dhyāna; being of diverse kinds, the hundreds of thousands of teachings are ineffable. Because they are ineffable, though filled to capacity in dragon palaces or on elephant backs, though oceans were used as ink or mountains ground to inksticks, the eighty-four thousand dharma treasures could never be exhausted. Although indeed without boundary, when subsumed under the twelve genres, none is left uncollected.
