大乘起信論義記 2.211

2.211

○自下境界為緣生六種麁相，即分別事識也。如《楞伽經》云「境界風所動，種種諸識浪」等，此之謂也。

From here on, with the objective realm as the condition, the six kinds of coarse marks are produced, which are the differentiating empirical consciousness. As the Laṅkāvatārasūtra says: “Stirred by the wind of objective realms, the waves of the various consciousnesses [arise],” and so forth; this is what is meant.
