成唯識論演祕 2.17

2.17

This reveals cognitive resistance, where grasping is like leaning on and reflecting upon [an object]. The nature of mind and mental factors is frail and weak; they do not arise without an object, just as a frail person does not rise without a cane. Therefore, those objects are what the mind reflects upon, and are called intentional objects. This is stated on the basis of their functioning only arising when there is an object, not that they must be functioning right now; therefore, past and future minds are also said to have resistance. Being obstructed in the function of cognizing an object is called cognitive resistance.
