Hell is People

The great mosque in Damascus is a visual depiction of Paradise.

Seeing these pictures of beautiful buildings, succulent fruit and plenty of water, one realizes that all of these delights are well within the capacities of humans today ... not only these delights, but much more. 

Furthermore, this vision of Paradise exists in the physical world today, in may places.  Among these places, many are a pleasure to live in, but for others living, or more likely existing, there, it is Hell.

So, what one can conclude is that Paradise is not Paradise because of its architecture and accoutrements, but because of the people who live there and how they treat each other.
