Who watches you? You must have noticed that something, all of your life, has been aware of you. When you were a baby it was pure Awareness. Out of a babies eyes there is nothing but Seeing. When the thought "I" appears, it makes it seem as if there are two "somethings" going on ... "I" and the "Awareness" that is aware of the "I." But the "I" is not real, it is just a thought, like all thoughts that appear.
Begin to Notice who is watching, who is Aware that the "I" thought has appeared? Begin to put your attention on that, like a baby who does not need to know who is watching, you don't need to know or search for who is watching, just begin to put your attention on it.
It (which is not an "it") has always been watching, so this is not something to be concerned about, it is something to place the attention on. Begin to notice that you do not know "who" is watching, but have the willingness to begin to be willing to Know who is watching, not by understanding, by pure Awareness.
