2.118

[Treatise:] "All these [dharmas are fundamentally... inexpressible marks...]" [Commentary:] This cites the extensive to seek by analogy. Because the aforementioned defiled and pure dharmas are mutually dependent designations, all dharmas fundamentally have no self-nature; they are not born from expedient means following awakening. Therefore it says, "therefore from the beginning," and so on. Because the two grasps do not exist, they are neither form nor mind; because the mind has no defilement or purity, it is not consciousness; since they have no arising or ceasing, they are neither existent nor non-existent. Hence, they are ultimately inexpressible marks.
