"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 life's 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."
