US-P18.135ab ।US-P18.135cd ॥
In plain words
If ignorance is granted to belong to the object itself, then when it is known another act of cognition must follow; and if ignorance belongs to something else, its persistence is certain upon that object being known.
Close to the Sanskrit
If ignorance of that very object is accepted, another act of cognition would arise upon it being known; and in the ignorance of another, [ignorance] would certainly arise upon the special knowledge of that.
