“When a Tathagata is pressedthree times, he has to answer. Listen carefully, Bahiya, andattend to what I say: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.Thus you should see thatindeed there is no thing here;this, Bahiya, is how you should train yourself.Since, Bahiya, there is for youin the seen, only the seen,in the heard, only the heard,in the sensed, only the sensed,in the cognized, only the cognized,and you see that there is no thing here,you will therefore see thatindeed there is no thing there.As you see that there is no thing there,you will see thatyou are therefore located neither in the world of this,nor in the world of that,nor in any placebetwixt the two.This alone is the end of suffering.” (ud. 1.10)Upon hearing these words, Bahiya was immediately enlightened.
when i find myself wanting something do be different than it is,or want somebody else be different , then there is one line , one question,one reminder, that is very powerful to me. i ask myself "WHO wants this?" it acts like a mirror that often pulls me out of self-identification.its sort of a post-it in my brain ..
