“Just as the awareness of wrong becomes increasingly deep in Hell, the understanding and enjoyment of good grow constantly stronger in Paradise.
Unlike Hell, which is a limited, finite stage, because it has to correct and amend what happened in a finite span of life, the joys of Paradise are endless and everlasting.
To use a physical metaphor, the absolute zero of temperature is defined and closed.
But there is no upper limit to higher and higher temperatures.
The freed, cleansed soul is now able to have a touch of Godhead, which is the absolute infinity that contains the wholeness of everything.
While being connected and confined by the body and by the shadows of the world, the soul can hardly grasp it.
But in another stage of existence, when these boundaries are no longer there, the soul can keep ascending for eternity.”
