In fact, we don't know objects; we just know 'knowing'. And who is it that knows 'knowing'? 'Knowing' is not known by something or someone outside or other than itself. 'Knowing' is known by 'knowing'. In other words, all that is experienced in the experience of an object, other or world is 'knowing'.
