You are undoubtedly here, present. The only commonality of a lifetime of experience has been this always-here-ness, this presence. Everything else has changed, the body, the thoughts, the feelings, emotions, sensations....
What-you-are is just simply HERE. There isn't anything else to say about it. It cannot be described, because it's not objective like the rest of it, like all experiences. It isn't an experience. It's just your presence. It's just the present activity of knowing. It's going on right now. It's here. It's unmistakably and obviously here. It's how the world is known. It's how the body is known. It's how thoughts are known.
It's how anger, frustration, sadness, and every other feeling or emotion is known.
It's not objective. It's not an experience. It's the experiencING. The knowing. Can you deny that? Are you ever without it? Does it leave? Does it change? Does it come and go?
No. It does not. It's not difficult. It doesn't require searching. It's that IN WHICH the search takes place, the idea of seeker takes place.
It's not personal - the personal is the quality of the body, of thoughts. You are THAT which knows the personal.
It's not individual - the individual is appearance - objective - quantifiable, measurable, changing.
It's just this present knowing - this subjective "I"-ness. It's always here.
You are looking FOR your true Self, when all the while you are already looking FROM your true Self.... Just notice.
