There is nothing more important for life, even for material life, than the strong and sure realization of communion with the spiritual world.
If modern men had not lost their relationship with spiritual things to such an extent, these grave times would not have come upon us. Only a very few today have insight into this connection, although it will certainly be recognized in the future. Today men think: When a human being has passed through the gate of death, his activity ceases as far as the physical world is concerned. But indeed it is not so! There is a living and perpetual intercourse between the so called Dead and the so-called Living. Those who have passed through the gate of death have not ceased to be present; it is only that our eyes have ceased to see them. They are there in very truth.
