維摩經玄疏 5.69

5.69

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.
