Now, however, the dawn of the sixth post-Atlantean era of civilization is already at hand. What is to arise at a certain time in human evolution has ripened slowly in the preceding age. The first beginnings of that which can even now be developed, is to be discovered in the thread which binds together the two tendencies of the human breast, material civilization and life in the spiritual world. To this end it is necessary, on the one hand, that the results of spiritual vision should be understood; and on the other, that in the observations and experiences of of the sense-world the revelations of the Spirit be recognized. The sixth civilization-epoch will bring to full development the harmony between the two. Herewith the studies in this book have reached a point where we may turn from the perspectives of the past to those of the future. But it will be better to precede the latter by a study of the Knowledge of Higher Worlds and of Initiation. Then, after this study and in connection with it, we shall be able to indicate in brief the outlook for the future, in so far as that can be done within the framework of this book. CHAPTER V. KNOWLEDGE OF THE HIGHER WORLDS At the present stage of evolution there are three possible conditions of soul in which man ordinarily lives his life between birth and death: waking, sleeping and, between the two, dreaming. The last-mentioned will be briefly dealt with in a later part of this book; for the moment we shall consider life simply as it alternates between its two main conditions—waking and sleeping. Before he can “know” for himself in higher worlds, man has to add to these two a third condition of soul. During waking life the soul is given up to the impressions of the senses, and to the thoughts and pictures that these evoke in it. During sleep the senses cease to make any impression, and the soul loses consciousness. The whole of the day’s experience sinks down into the sea of unconsciousness. Let us now consider how it would be if man were able to become conscious during sleep, notwithstanding that all impressions of the senses were completely obliterated, as they are in deep sleep. Now would any memory remain to him of what had happened while he was awake. Would his soul find itself in a state of vacuity? Would it be incapable of having any experiences? This is a question that can only be answered if conditions like or similar to those under discussion can actually be brought about. If the soul is capable of experiencing anything, even when sense-activities and recollection of such activities are lacking, then that soul would, so far as the external world is concerned, be “asleep”; and yet the soul would not be sleeping but awake to a world of reality.
