維摩經玄疏 5.115

5.115

答曰：若不思議解脫離思議，終非不思議。如無餘涅槃無所思惟，即是不離不思議有不思議也。故此經云：「能善分別諸法相，於第一義而不動。以於諸法得自在，是故稽首此法王。」於諸法得自在者，即是於六識思議分別法中得自在，名不思議解脫也。

Answer: If inconceivable liberation were separate from the conceivable, it would ultimately not be inconceivable. Just as nirvāṇa without remainder has no deliberation, this means inconceivable is not separate from conceivable. Hence this sūtra says: 'Skillful at discriminating the marks of all dharmas, yet unmoving regarding the ultimate truth. Having attained mastery in all dharmas, therefore I bow my head to this Dharma King.' Attaining mastery in all dharmas means attaining mastery amid the conceivable and discriminating dharmas of the six consciousnesses; this is called inconceivable liberation.
