妙法蓮華經玄贊 8.287

8.287

釋名者，可軌可持名之為法，可習可範目之為師。此教可軌、此理可持雙名為法，此法可習名為法師。故《涅槃》云：「諸佛所師，所謂法也」，《遺教經》言：「波羅提木叉是汝大師」。此品之中讚經可重，法即是師故名法師。此法為法師，能學法者可為摸範訓匠群物，有法之師名為法師。此人、法師，此品廣明，名法師品。品下雙說法及學者並名法師，義通為勝。

Regarding the explanation of the title: That which can be taken as a standard and upheld is called "Dharma"; that which can be practiced and taken as a model is designated as "teacher". This teaching can serve as a standard, and this principle can be upheld—both are called "Dharma"; this Dharma can be practiced, so it is called a "Dharma teacher". Thus the Nirvāṇa [Sūtra] says: "The teacher of all buddhas is what is called the Dharma"; the Sūtra of the Buddha's Bequeathed Teaching says: "The prātimokṣa is your great master." Within this chapter, the sūtra is praised as worthy of veneration; the Dharma itself is the teacher, hence it is called "Dharma teacher". This Dharma serves as the teacher of the Dharma, and those who can learn the Dharma can become models to instruct and fashion the masses; a teacher who possesses the Dharma is called a "Dharma teacher". Both this person and the Dharma are teachers, which this chapter broadly clarifies; hence it is called the "Dharma Teacher Chapter". Below in this chapter, both the Dharma and the practitioner are called "Dharma teacher"; encompassing both meanings is superior.
