At the moment of death, when the human being goes through the portal of death, he sees numerous hindering, malevolent forces approaching him. These forces, however, are usually drawn near through the fear of death. The greater the fear of death, the stronger their power is. Fear of death has always been a cause of anxiety at the moment of death. When, however, the dying person is aware that fear cannot change anything about the dying process that he has to go through, these forces and powers appear like desiccated bags.
The human being can only gain victory over the fear of death and bravely face it if he knows that in him is an immortal, eternal inner core for whom death is only a metamorphosis of life, a change of life form. As soon as the human being discovers his immortal inner core through spiritual science, he learns more and more how to overcome anxiety and in the long run all fear of death disappears as well. The more materialistic a person is however, all the more will he fear death.
