But if a man becomes attached to the literal meaning of words and holds fast to the illusion that words and meaning are in agreement, especially in such things as Nirvana which is unborn and un-dying, or as to distinctions of the Vehicles, the five Dharmas, the three self-natures, then he will fail to understand the true meaning and will become entangled in assertions and refutations.

(The Lankavatara Sutra)
