肇論新疏 1.128

1.128

通前違妨也。復謂研復。聖言，即前無常教也。微隱難測者，以言權旨實故，《涅槃》名為「密語」。大乘智臣善識密意。意謂雖談無常亦密顯真常，不可守言一向作無常解也。以二法相待，有此定有彼故。若動下，出難測所以。若說即無常之動是真常之靜，似說一人即去而元不去也，難測在此。

This resolves the previous objection. 'Examining further' means investigating repeatedly. 'The sages' words' refers to the teaching of impermanence mentioned earlier. As for 'subtle, hidden, and hard to fathom,' because the words are provisional while the purport is real, the *Nirvāṇa-sūtra* calls them 'secret words.' The wise ministers of the Mahāyāna skillfully recognize the secret intent. The meaning is that although it speaks of impermanence, it also secretly reveals true permanence; one must not cling to the words and exclusively interpret it as impermanence. Because the two dharmas are mutually dependent: if this exists, that definitely exists. From 'seeming to move' down, [the text] explains why it is hard to fathom: if one says that the movement of impermanence is itself the stillness of true permanence, it is like saying that a person departs yet fundamentally never departed; the difficulty in fathoming lies right here.
