"Then, Bahiya, you should train yourself thus: 
in the seen, there is only the seen; 
in the heard, only the heard; 
in the sensed, only the sensed; 
in the cognized, only the cognized. … 
When for you [there are only those things] …, 
then, Bahiya, there is no you … 
This, just this, is the end of suffering."

[The Buddha, in Bahiya-sutta]
