維摩經玄疏 5.69

5.69

一、通釋思議、不思議解脫者，對思議解脫明不思議解脫，若解思議之理而脫緣縛者，名思議解脫；若解不思議之理而脫緣縛者，名不思議解脫。思議解脫即是離文字之解脫，故身子答天女云「吾聞解脫，無有言說」。若不思議解脫，即是不離文字之解脫，故天女云「無離文字，說解脫相」，文字性離，即解脫也。

First, as for generally explaining conceivable and inconceivable liberation: clarifying inconceivable liberation in contrast to conceivable liberation, if one understands the principle of the conceivable and thereby becomes free from the bondage of conditions, this is called conceivable liberation; if one understands the principle of the inconceivable and thereby becomes free from the bondage of conditions, this is called inconceivable liberation. Conceivable liberation is liberation apart from words; thus Śāriputra answered the goddess, saying, 'I have heard that liberation has no spoken explanation.' Inconceivable liberation is liberation not apart from words; thus the goddess said, 'Without departing from words, speak the characteristic of liberation'; the nature of words being detached is itself liberation.
