注大乘入楞伽經 7.169

7.169

言若人不善說法，墮文字言教者，名虛誑說。三世如來及諸菩薩其實未甞說答一字，諸法性相離故，亦非不隨真實義故，假分別說以顯耳。

This means that if someone is not skilled at expounding the Dharma and falls into letters and verbal teachings, it is called false and deceptive speech. In reality, the Tathāgatas of the three times and all the bodhisattvas have never once spoken or answered with a single character. This is because the nature and characteristics of phenomena are dissociated [from speech], yet it is not that they do not accord with the real meaning, as they provisionally make discriminating explanations to reveal it.
