妙法蓮華經玄贊 3.20

3.20

二教化成就，謂種種知見示現染淨諸因故。由具知見，於化身中能示現有一切染因集能招苦，一切淨因道能證滅，或示現染淨諸法道理。因者所以、道理義故。前能現身，此於身中示有諸法染淨道理。論下解此與第四別，此依證法，彼依說法故。

Second, the accomplishment of teaching and transforming: that is, with various knowledges and visions, manifesting the various causes of defilement and purity. Because he is endowed with knowledge and vision, he can, within his transformation body, manifest that the accumulation of all defiled causes can bring about suffering, and the path of all pure causes can realize cessation; or he manifests the principles of all defiled and pure dharmas. 'Causes' has the meaning of reason and principle. The former is able to manifest the body, whereas this manifests within the body the defiled and pure principles of all dharmas. Below, the Treatise explains that this differs from the fourth: this relies on the realized Dharma, whereas that relies on the expounded Dharma.
