All these people are perfectly happy.

Later on they will reach a stage when they can appreciate something much higher, and when that stage comes they will find the higher ready for them.
In this astral life people of the same nation and of the same interest tend to keep together, precisely as they do here.

The religious people, for example, who imagine for themselves a material heaven, do not at all interfere with men of other faiths whose ideas of celestial joy are different.

There is nothing to prevent a Christian from drifting into the heaven of the Hindu or the Muhammadan, but he is little likely to do so, because his interests and attractions are all in the heaven of his own faith, along with friends who have shared that faith with him.

This is by no means the true heaven described by any of the religions, but only a gross and material misrepresentation of it; the real thing will be found when we come to consider the mental world.
The dead man who has not permitted the rearrangement of the matter of his astral body is free of the entire world, and can wander all over it at will, seeing the whole of whatever he examines, instead of only a part of it as the others do.
