首楞嚴義疏注經 2.545

2.545

彼若救云：我此見性雖不與暗合，無妨見暗，斯有何失？故此牒云：若見暗時不與暗合，隨即破云：與明合者應非見明。若許不合有見，即應合必無見，復云何言見與明合，了明非暗？故知見明而無合義。和合見性既而不成，菩提證心因和合有，從茲破矣。

If he defends [his position] by saying: 'Although this nature of my seeing does not join with darkness, that does not prevent it from seeing darkness—what fault is there in this?' Therefore this [text] cites: 'If when seeing darkness it does not join with darkness,' and immediately refutes it: 'Then one that joins with light ought not to see light.' If one concedes that there is seeing without joining, then joining must entail no seeing. How then could one say that seeing joins with light, and clearly knows light and not darkness? Hence we know that seeing light does not have the meaning of joining. Since a blended or joined nature of seeing cannot be established, the bodhi-realizing mind existing on account of blending and joining is hereby refuted.
