For the mind in harmony with the Tao,
all selfishness disappears.
With not even a trace of self-doubt,
you can trust the universe completely.
All at once you are free,
with nothing left to hold on to.
All is empty, brilliant,
perfect in its own being.
In the world of things as they are,
there is no self, no non-self.
If you want to describe its essence,
the best you can say is "Not-two."
In this "Not-two" nothing is separate,
and nothing in the world is excluded.
-poem by Seng Tsans (died A.D. 606)
