瑜伽論記 2.176

2.176

示正義有六：一、處遠離難取；二、四障難取，如前第三卷說：一覆蔽障等；三、微細難取，如極微等；四、心亂難取，如神通境等；五、根壞難取，如老昧病等；六、無智難取，如無他心智，故不取他心等，如此諸法雖有，而不可取故，汝不應說有性法皆是有、皆可顯了。

There are six points illustrating the correct doctrine: 1. Difficult to grasp due to remoteness of location. 2. Difficult to grasp due to the four obstructions, as explained earlier in Fascicle 3: the obstruction of concealment and so forth. 3. Difficult to grasp due to minuteness, like infinitesimal particles (paramāṇu) and the like. 4. Difficult to grasp due to mental distraction, like the objects of supernormal powers (ṛddhi) and the like. 5. Difficult to grasp due to sensory impairment, like senility, dullness, illness, and the like. 6. Difficult to grasp due to lack of knowledge, like not grasping another's mind due to lacking the knowledge of others' minds (paracittajñāna). Since these dharmas, although existing, cannot be grasped, you should not say that all dharmas having an intrinsic nature exist and can all be manifested.
