It was also in this conviction that the positive duty of burying the deceased originated. In order to bring rest to the soul in the subterranean dwelling that fitted its new existence, it was necessary that the body, to which, in some way or another, it still clung, should be covered with earth. The soul, denied a grave, had no dwelling. Drifting about, it sought in vain the desired rest after lifes fitful struggle. Without shelter, without offerings or food, it was condemned to everlasting wandering. Therefore, because the deceased was unhappy, he became illnatured. He tormented the living; sent them diseases; destroyed their harvests; haunted them in uncanny visions in order to remind them of their duty to bury the body and thereby secure peace for himself.
