維摩經玄疏 1.140

《方等》四番悉檀赴緣說四番聖諦故，名「聖說法」；生生、生不生、不生生、不生不生不可說故，名「聖默然」。

In the Vaipulya, four rounds of siddhāntas respond to conditions to preach the four rounds of noble truths, which is called 'noble preaching of Dharma'; because the arising of arising, the arising of non-arising, the non-arising arising, and the non-arising non-arising are ineffable, it is called 'noble silence.'
