楞伽阿跋多羅寶經註解 1.493

1.493

此既二乘入滅盡定，以例微細藏識不滅之義。蓋二乘之人入此定，不能知是識轉，自謂我因滅諸識而入正受，而實未嘗滅也。不滅者，以識之習氣種子依藏識故也。彼滅盡定但伏六識，不取塵境以為滅耳。攝受不具者，即不取塵境也。

This uses the two vehicles' entry into the cessation attainment to illustrate by analogy the principle of the non-cessation of the subtle storehouse consciousness. When practitioners of the two vehicles enter this attainment, they cannot know that this is the evolution of consciousness; they tell themselves, 'It is because I have ceased the various consciousnesses that I have entered the correct attainment.' Yet in reality it has never ceased. The reason it does not cease is that the seeds of vāsanā of consciousness rely upon the storehouse consciousness. That cessation attainment merely suppresses the six consciousnesses and does not grasp at dust realms, which they consider to be cessation. 'Grasping is incomplete' means precisely not grasping at dust realms.
