十二門論宗致義記 1.28

1.28

第三、顯德用者，《中論》云「以有空義故，一切法得成」，又云「以一切法空故，得有三寶四諦等」。《大品》云「若一切法不空，則無道無果」，又云「若諸法如毫釐許有者，則諸佛不出世」。如是等文皆明以有真空故方有諸法也。又由觀真空方成諸行，是故十度等行皆由空成，菩提等果皆由空立，是故從此真空無住建立諸法。又令諸法得相即相入無障無礙等，並是此門之大用也。

Third, revealing virtues and functions: the Madhyamaka Śāstra states: 'Because there is the meaning of emptiness, all dharmas are able to be established.' It also states: 'Because all dharmas are empty, there can be the Three Jewels, the Four Truths, and so forth.' The Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra states: 'If all dharmas were not empty, there would be no path and no fruition.' It also states: 'If dharmas existed even by a hair's breadth, then buddhas would not appear in the world.' Such passages all clarify that only because true emptiness exists can there be all dharmas. Furthermore, only by contemplating true emptiness are all practices accomplished; therefore, practices such as the ten perfections are all accomplished through emptiness, and fruitions such as bodhi are all established through emptiness. Therefore, all dharmas are established from this non-abiding of true emptiness. Furthermore, causing all dharmas to be mutually identical and mutually penetrating without impediment or obstruction—these are all the great functions of this approach.
