摩訶止觀 4.131

4.131

法性亦具三義：境是所師，冥熏密益，即是外護。境智相應，即是同行。未見理時如盲，諦法顯時如目，智用無僻。經言：「修我法者，證乃自知；心無實行，何用問為？」即教授也。

Dharmatā also possesses the three meanings: the objective realm is what is taken as teacher, and its dark perfuming and secret benefit is the external protector. The correspondence between the objective realm and wisdom is the fellow practitioner. When one has not yet seen the principle, one is like the blind; when the Dharma of the truths becomes manifest, one is like having eyes, and the functioning of wisdom is without distortion. A sūtra says: "Those who cultivate my Dharma know it for themselves through realization; if the mind has no actual practice, what use is asking?" This is the teacher.
