Lecture I
When with clairvoyant vision we penetrate the spiritual worlds, it seems to be of special importance that at the present time and in the near future knowledge of the spiritual world should be made more and more widely known, because the change in man's soul-life, which is so necessary now and will become more and more necessary, will greatly depend upon the spreading of Spiritual Science. You see, if we look back with spiritual vision even but a' few centuries to olden times, we come upon something which must greatly surprise anyone ignorant of these things. We find that the intercourse between the living and the dead is becoming increasingly difficult, and that a comparatively short time ago there was a much more active intercourse between them.
