The ability to relate to the end of days is limited not only by shortcomings of human nature, but also by something more basic: limitations in the nature of reality.
Reality allows us to relate only to things that belong to the plane of being, experience, and action in which we exist.
Just as we cannot fit a large object into a small receptacle, we cannot fit anything into a vessel – a concept, a description, or a figment of our imagination – that cannot receive or contain it.
Rabbi Adin Steinsaltz
