The Buddha to Bahiya:
' 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 cognized there is only the cognized:
This, Bahiya, is how you should train yourself.
When, Bahiya, there is for you
in the seen only the seen,
in the heard only the heard,
in the sensed only the sensed,
in the cognized only the cognized,
then, Bahiya, there is no 'you'
in connection with that.
When, Bahiya, there is no 'you' in connection with that,
there is no 'you' there,
When, Bahiya, there is no 'you' there.
When, Bahiya, there is no 'you' there.
then, Bahiya, you are neither here
nor there
nor in between the two.
This, just this, is the end of suffering. '
