The first time I heard somebody say that, I didn’t like the sound of it one bit. What else could I be? I had taken for granted that the mental chatter in my head was the central “me” that all the experiences in my life were happening to. I see quite clearly now that life is nothing but passing experiences, and my thoughts are just one more category of things I experience. Thoughts are no more fundamental than smells, sights and sounds. Like any experience, they arise in my awareness, they have a certain texture, and then they give way to something else. If you can observe your thoughts just like you can observe other objects, who’s doing the observing? Don’t answer too quickly. This question, and its unspeakable answer, are at the centre of all the great religions and spiritual traditions.
