Words and sentences are produced by the law of causation and are mutually conditioning, they cannot express highest Reality. Moreover, in highest Reality there are no differentiations to be discriminated and there is nothing to be predicated in regard to it. Highest Reality is an exalted state of bliss, it is not a state of word-discrimination and it cannot be entered into by mere statements concerning it. The Tathagatas have a better way of teaching, namely, through self-realization of Noble Wisdom.

(The Lankavatara Sutra)
