I agree that the object of grasping takes up space in the mind proportional to the level of intensity of the grasping. I learned that the object of grasping is never as important or solid as I think it is, and that perception and realization opens up space, helps me grasp less, and helps dissolve the vicious cycle of false solidity. I find the object is transient and doesn't bring what is sought. I've also learned that grasping contracts mind space and is a source of unnecessary suffering. Not grasping results in more mind space and helps me be freer and more happy and at peace. Those lessons help me incline the mind to notice space.
