首楞嚴義疏注經 5.81

5.81

This is because the earlier verse said: "Untying knots depends upon sequence; / When the six are untied, the one also vanishes." The sense of Ānanda's doubt is: Since the earlier text stated that faculties and dusts share the same origin, and bondage and release are not two, delusion and obscurity being avidyā while illumination is liberation, then knots have no before or after, and untying them has no sequence either. If the six faculties vanish, the single awareness should become manifest; why then does he speak again of "untying knots depends upon sequence" and "when the six are untied, the one also vanishes"? Thus he says his mind is not yet clear and prays for defilements to be washed away.
