Because we are troubled by having a self.
Why do we say that honor and dishonor move us?
Because honor lifts us upward
And dishonor lowers us downward.
Thus, when we are honored we are moved;
When we are dishonored we are also moved.
That is why honor and dishonor are both said to move us.
Why do we say that the great trouble is having a self?
Because we have great trouble simply because we have a self.
If we are selfless, then where is the trouble?
If we identify our self with the world,
Then within our self there is the world.
If we love the world as we love our self
Then within our self there is only the world.
--- Chang Chung-yuan, 1975.
