三、明生了因者，謂塵體空寂，緣起法界之義，由智方顯，是了因。見塵體已，修於解行，生起力用，是生因。然生即無生，還同法體；了亦非了，豈等緣生。生之與了無有差別，生則約行，了則據體。無體即體，了則無生，體即無體，生還為了，契同一際，無所分別。

Third, clarifying producing and revealing causes: the dust mote's essence being empty and still, the meaning of the conditioned origination of the dharmadhātu is revealed only through wisdom, which is the revealing cause (vyañjaka-hetu). Having seen the dust mote's essence, cultivating understanding and practice to give rise to power and function is the producing cause (janaka-hetu). However, production is precisely non-production, returning to identity with the essence of phenomena; revealing is also non-revealing, for how could it equal conditioned arising? Between production and revealing there is no difference: production is spoken of in terms of practice, while revealing is based on essence. The non-essence is precisely essence, so revealing is unarisen; essence is precisely non-essence, so production returns to revealing; they accord in a single realm, without discrimination.
