In plain words
Take the sentence at its literal word and a contradiction appears — perception and the other means of knowing object to it. So the plain sentence-meaning will not hold. Let me tell you exactly what that contradiction is.
Close to the Sanskrit
In the case of (its) being the sentence-meaning, there is a contradiction produced by perception and the rest; therefore the sentence-meaning does not hold together. And that contradiction I state to you.
