As to the idea of what is called heaven and hell-for our comprehension these are two places: one where a person is punished, the other where he is exalted, where he is happy, where he is rewarded. This idea is clear, but where do we experience all unhappiness and sorrow and discomfort, and where do we experience all pleasure and happiness and joy? Is it not on the same earth? It is under the same sun. This explains to us that those two places were shown to us as different because we are capable only of seeing them as two different places. The wise of the world, at any time of the world's civilization, could not do better than to make the subtle ideas of life as simple and comprehensible to man as possible.
