成唯識論演祕 5.383

5.383

如有問彼十四事者，不應為釋，無義利故，名不可記。其十四者，按《大般若經》云：世界常耶、無常耶、亦常無常耶、非常非無常耶，為四。世間有邊、無邊等，為四。如來死後有耶、無耶、亦有亦無耶、非有非無耶，為四。命與身一為一、命與身異為一。合為十四。

If someone asks about those fourteen matters, one should not explain them; because they lack benefit, they are called undeclared (avyākṛta). As for these fourteen, according to the Mahāprajñāpāramitā-sūtra: 'Is the world eternal? Is it non-eternal? Is it both eternal and non-eternal? Is it neither eternal nor non-eternal?'—these make four. 'Is the world finite? Is it infinite?' and so on make four. 'Does the Tathāgata exist after death? Does he not exist? Does he both exist and not exist? Does he neither exist nor not exist?'—these make four. 'Are the life-principle (jīva) and the body identical?' is one; 'Are the life-principle and the body different?' is one. Together they make fourteen.
