因明入正理論疏 1.13

1.13

五、言因明、正理，俱陳那本論之名。入論者，方是此論之稱。由達此論，故能入因明正理也。或因明者，即入論名。正理者，陳那教稱。由此因明論，能入彼正理故。或因明者，能入所入論之通名。入正理者，能入所入論之別稱。由此因明能入論故，達解所入因明正理。或此應云：因即是明，正者即理，並持業釋。

Fifth: both 'hetuvidyā' and 'nyāya' are the names of Diṅnāga's root treatise. 'Entering treatise' is only then the designation of this treatise. Because one penetrates this treatise, one is able to enter into the hetuvidyā and nyāya. Or 'hetuvidyā' is itself the name of the entering treatise. 'Nyāya' is the designation of Diṅnāga's teaching. This is because by means of this hetuvidyā treatise, one is able to enter that nyāya. Or 'hetuvidyā' is the general name of both the treatise that enters and the treatise that is entered. 'Entering the correct principle' is the specific title of the treatise that enters and the treatise that is entered. Because of this hetuvidyā being the treatise that enters, one penetrates and understands the hetuvidyā and nyāya that are entered. Or here one should say: the cause is itself the illumination (science), and the correct is itself the principle, both being karmadhāraya compounds.
