For one thing, there is the obvious, namely that when you do not think, you still ARE. In the pauses between thoughts your identity does not disappear.
And notice that you can step back and look down at your thoughts, you can watch them flow by. Ask yourself, “Who is this watcher?”
“Have you ever beheld in surprise A self looking out of your eyes Gazing back from the mirror at you -A stranger majestic and wise…
A mystery, burning, immense, Flashing suddenly into your new, Astounding, intense As lightening out of the blue?
Have you seen how the stranger withdrew To the depths of your wondering stare, While you, when your longing would dare, Made questioning: “Who are you?” Marveling half in fear, “Who is the stranger here?” Why have we never met before At the eyes mysterious door?”
For another, a basic realization that comes from deep meditation and spiritual experience is the direct realization that we are not body, emotions, or mind but we are, in fact, that which lies back of these and expressed through them.
“Don’t be so loyal to your mind; the mind is not loyal to You.”
― Bert McCoy
“Only once in a while you become aware of your intrinsic nature, with sudden bursts of empty spaces, without any effort on your part, you come home, rejoice every breath so deep and so soothing, you relax, unfocused, you skip into timelessness. This is the greatest mystery, the greatest gift of existence, without any identification to your senses, no clutches of your old patterns of mind. Few Glimpses of Heaven on the earth! I have experienced, have you?”
