The mind is always like a reporter at a funeral. It's a completely inappropriate jerk who has no compassion whatsoever. In the West we have highly over-valued thinking. So, I can tell from what you are saying that you are really passionate about this overthrow of the mind. It is the first step.
Truth is the truth of our experience.
Three things you can depend on, what's radically honest, is that you know what you feel, you know what you think when you are observing your thoughts, and you know what's going on outside of you. You can arbitrarily break awareness into three parts. I can report to you as a witness what's going through my mind. I can report to you as a witness what I am noticing outside of me, and I can report to you as a witness what I notice within the confines of my own skin. When I am making such reports I am telling the truth.
