The truth is so very simple that it's almost impossible to see.
First, the "ultimate truth" are words that point back to us. What are we really? Forget everything else. Who am I???
So what is it in our life -- right here, right now --that keeps pointing back to the truth of what we are. Surely, if it's genuine truth of our being is not going to be hidden, but rather very, very blatant. And so it is.
Hold a rock in your hand. It's clearly not you because it is an object of observation. You are witnessing it. Same goes with all mind-generated thoughts and beliefs - you are witnessing them and so NOT them. Same goes with emotions and physical feelings -- you witness them, they are objective, and so you are not them. So what are you???
You are no thing that can be seen, heard, or felt. You are the silent, indescribable, untouchable, pure witness that is aware of what we call our "life and universe".
What is really amazing is that it is the very same witness within all of us. We are not separate, but one in the same – which points to the word LOVE, which is not what this thread is about.
