一、三品不成失。景云：若彼明無是無明者，明無即是無性，無性之法無有三品，而佛結無明有上中下，故知無明非無明也。應立量云：汝立無明應無有體，無三品故，猶如兔角。

First, the fault of the three grades failing to be established. Jing says: if that absence of brightness were ignorance, the absence of brightness would be non-existence, and a dharma without nature has no three grades; yet the Buddha concluded that ignorance has superior, middling, and inferior grades; thus we know that ignorance is not the absence of brightness. One should establish the syllogism: 'The ignorance you posit should have no entity, because it lacks three grades, like a rabbit's horn.'
