二、安住乃至或復安立穩密顯了記別差別者，隱密說者，謂有問我與世間常無常等，但語彼云我說此不可說，名隱密說。顯了說者，有如法問，還如法記等。

2. From 'abiding' up to 'or establishing the distinctions of concealed and explicit declaration': concealed explanation means that when someone asks whether the self and the world are permanent or impermanent and so forth, merely telling them, 'I declare this to be inexpressible,' is called a concealed explanation. Explicit explanation means that when there is a question according with the Dharma, one replies according with the Dharma, and so forth.
