The mind cannot come to terms with it.
Like a veil, the concepts you have about the world and your self create a false reality, a reality of "things". As a "thing", you will always be limited by all that you are not.
Lay aside all concepts and paradigms - rest only as your Self. The various concepts about what you are will continue to splash against the screen, like a stormy ocean. Don't worry.
That pure Self is empty of all content. You simply ARE - nothing more can be said. The first attempt to grasp it, to place a category, to label it, to quantify it, is the very content of that veil.
Be content with silence - stillness. That stillness remains as the background, the silent activity of knowing which can never be negated.
You ARE - even that is a concept.
