In the Q&A session, taking an excerpt, it reminds me of the questions and answer sessions we have in Parayanavagga.
Q: It seems as if you are saying there is something else outside of the conventional body-mind (five khanda). Is there something else? What do you call it?
Ajahn Chah: There isn't anything and we don't call it anything -- that's all there is to it!
In the ParayanaVagga Buddha insists to the brahmin Mettagu, "whatever you discern above and below or all around there is nothing there".
These brahmins of the "Way to the Beyiond" had meditated for many years, had their own followings, revered by many, were puzzled by Buddha's statements, just as much as some are puzzled by Ajhan Chah's answer.
"Be finished with all of it. Even the knowing doesn't belong to anybody, so be finished with that, too!"
Elsewere Buddha says "kill the consciousness" it is the culprit, it expresses itself via feeling, perception, and mental disposition or Papanca. Basically this consciousness is a conduit to suffering.
Consciousness is not an individual, not a being, not a self, not an other, so finish with that -- finish with everything! There is nothing worth wanting! It's all just a load of trouble. When you see clearly like this then everything is finished.
Remember the sutta on "The burden"?, Sutta writes "unload the burden"
Buddha advices Mettagu in Parayanvagga "Let not your consciousness abide in being"
implying "Don't offer a house to your consciousness. Make it homeless." I don't find Ajhan Chah's
response any different. Certainly the wording is different.
