Now, the contradictory: the contradictory is that which conflicts with examples, established tenets, or conventions. Among these, examples and established tenets have been mentioned earlier. Convention, moreover, is threefold; namely: medical convention, sacrificial convention, and liberation-treatise convention. Among them, medical convention is: 'Medicine has four limbs'; sacrificial convention is: 'Animals are to be slaughtered by the sacrificers'; liberation-treatise convention is: 'Non-violence towards all living beings.' There, what is stated contrary to one's own convention is contradictory.
