From the Bahiya Sutta

In the seen, there is only the seen.
in the heard, there is only the heard.
in the sensed, there is only the sensed.
in the thought, there is only the thought.
This is how you should train yourself.
Since there is for you
in the seen, only the seen,
in the heard, only the heard,
in the sensed, only the sensed,
in the thought, only the thought,
and you see that there is no thing here,
you will therefore see that
indeed there is no thing there.
As you see that there is no thing there,
you will see that
you are therefore located neither in this,
nor in that,
nor in any place
betwixt the two.
This alone is the end of suffering.”
