成唯識論演祕 7.223

7.223

釋曰：由無分別智證彼真如，令彼煩惱悉皆空寂。而言「染法所不行」者，不為染法親所緣著，名「不行」也。四、名無相，如《疏》所引。五、名實際，無例所緣故。《釋論》云：「『實』者，謂無顛倒。此處究竟，故名為『際』。過無我性更無所求。」

The commentary states: Because non-conceptual wisdom realizes that tathatā, it causes those afflictions to be entirely empty and tranquil. As for saying 'defiled dharmas do not operate in it,' because it is not directly cognized and attached to as an object by defiled dharmas, it is called 'not operating.' Fourth, it is named the signless, as cited in the Commentary. Fifth, it is named the reality limit (bhūtakoṭi), because it has no parallel as an object. The Expository Treatise states: '"Reality" means non-inversion. Because this place is the culmination, it is named "limit". Beyond the nature of non-self, there is nothing further to be sought.'
