維摩經玄疏 1.143

1.143

《大般涅槃》四番悉檀赴緣說四番四聖諦故，名「聖說」，故《大涅槃》云：「說法者，諸佛境界。非諸聲聞、緣覺所知。」生生、生不生、不生生、不生不生不可說故，名「聖默然」，故佛答文殊「如來畢竟不轉法輪」，不轉法輪，即聖默然也。

In the Mahāparinirvāṇa Sūtra, four rounds of siddhāntas respond to conditions to preach the four rounds of four noble truths, which is called 'noble preaching'; hence the Mahāparinirvāṇa says: 'Preaching the Dharma is the realm of the buddhas, not what is known by śrāvakas and pratyekabuddhas.' 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'; hence the Buddha answered Mañjuśrī: 'The Tathāgata ultimately does not turn the wheel of Dharma.' Not turning the wheel of Dharma is precisely noble silence.
