In plain words
This "I" is something you see — so it is no more an attribute of the Self than a pot is. Understand every other notion the same way. And so the flaw is a stain on that seen self.
Close to the Sanskrit
Because of being seeable, this 'I' is not an attribute of the Self, like a pot and the like. Likewise the other notions are to be known; and therefore the defect is indeed a stain of the [seen] self.
