 When human reason is brought to bear on the diverse statements of the Buddha, it concludes that all statements that an essential or intrinsic identity exists, or any statements that presupposes that, cannot be taken literally, at face value. This is because human reason, when it analyzes the ultimate truth of any object or statement, finds it empty of anything intrinsic to it that would make it true. For Tsongkhapa, the line of reasoning that leads most clearly to this conclusion is dependent origination.
