首楞嚴義疏注經 10.355

10.355

此引前說結責未解也。如前文云「巾體是同，因結成異。」又云「畢竟同中生畢竟異。」又云「六結同體，結不同時，即結解時云何同除？」此皆理則頓悟、事非頓除，如何再問耶？頓漸悟修如《圓覺疏》。

This cites the earlier explanation to conclude with a reproof for not having understood. As the previous text states: "The substance of the cloth is the same, but due to the tying of knots, differences are formed." It also says: "From within ultimate sameness, ultimate difference is produced." It also says: "The six knots share the same substance, but their tying is not simultaneous; when untying the knots, how could they be removed all at once?" All these illustrate that "in principle, there is sudden awakening; in practice, they are not eliminated suddenly." Why ask again? For sudden and gradual awakening and cultivation, see the Commentary on the Sūtra of Perfect Enlightenment.
