Truly spiritual thoughts nourish our soul and maintain it. It would be the death of our soul if it always had to live in thoughts taken only from the physical world. In earlier times, religious beliefs were such spiritual thoughts human souls need. That phase of our development has been completed, and we live now in a time when we on earth will gradually lose the ability to take in what speaks only to our emotions, our faith.
We can still preserve this faith for a time, galvanizing it, so to speak, but we cannot keep it for the future. The principle “I believe” has to be replaced with “I believe what I know.” People will begin to feel that this new principle must be applied. Otherwise we deny ourselves any possibility of knowing something about the life between death and a new birth. Then we would return to pitiful conditions in our next incarnation.
