大乘起信論義記 3.351

3.351

初、於下不戀。二、若聞下，於上不怯。以信知下，釋不怯所以也。以此即顯彼經文是權非實故也。

First, not hankering after what is below. Second, from 'Even if they hear' onward, not being fainthearted regarding what is above. From 'because through faith they know' onward, it explains the reason for not being fainthearted. Through this it is shown that the text of that sūtra is provisional and not factual.
