注大乘入楞伽經 5.231

5.231

佛言我不對小乘說大乘，明佛乘非聲說文字，非實非虛，非解非縛，亦非有無境界。

The Buddha says: I do not speak of the Great Vehicle in contrast to the Small Vehicle; this clarifies that the Buddha-vehicle is not spoken sounds and written syllables, neither real nor unreal, neither liberation nor bondage, nor is it a realm of existence and non-existence.
