If I self-exist, how can I change?
How could I die?
For that matter, how could I have been born?
This is the simple contradiction that Nagarjuna uses to deconstruct self-being. That all phenomena appear and disappear according to conditions means that our usual way of perceiving the world as a collection of separately existing things is a delusion.
