The dead can experience their present spiritual environment only to the degree in which they formerly reflected, as much as earthly men are capable of doing, on the spiritual world. You know how many people are saying now-a-days: Why should I worry about life after death? We might as well wait. Once we are dead, we shall see what is going to happen. — This thought, however, is completely misleading. People who have not reflected, while still alive, on the spiritual world, who have lived in a purely materialistic way, will see absolutely nothing after death.
