The Souls Progress through Repeated Earth Lives

But what did a student acquire by going through these exercises in ancient India? He made the breathing process into something conscious, that is, he inhaled consciously. Through these exercises he gradually acquired the possibility of following the process that takes place when the pressure of inhalation causes the brain fluid to oscillate toward the brain through the spinal canal, and to strike, as it were, against the brain. It is this impact of the brain fluid against the solid parts of the brain (this brain fluid, which rushes upward during inhalation, falling again during exhalation), it is this impact that causes mental pictures to arise. The production of mental pictures is something much more complicated than is imagined today, when everything is thought out materialistically. Today it is thought—or at least it was until recently, for today people are no longer interested in thinking in clear concepts—it is thought that some kind of evolution, some nerves underlie the forming of mental pictures. This is nonsense. The real fact is that there is actually a constant striking of the brain fluid against the nerve system taking place which starts off those processes underlying the forces of the nervous system. The ancient Indian student of wisdom raised this activity to consciousness. What did he learn by following this whole process consciously? He learned from it how the underlying processes which had formed his brain really point back to former earth lives. Through his present rhythmic system he experienced, so to speak, his former earth life; this past earth life became a certainty to him. For such a student of wisdom it was simply self-evident that he had had a previous earth life. He could perceive it, you understand, by raising his breathing process to consciousness. Today this must be accomplished in another way. It cannot be brought about today by meditation that arises from a special way of shaping the breathing process; for this method must not be used by the modern human being. Quite the contrary, meditation today should proceed from a quiet dwelling on mental pictures: thus it starts out from the opposite side, and thereby takes into consideration the fact that modern man is much more closely united with his physical body. But by dwelling quietly on a mental picture, we learn to know this nuance of the rhythmic system from the other side, from the spirit-soul side. We come to know the process from the other side; in such a way, however, that we do not penetrate deeper into our body, as did the ancient Indian,—indeed we must not do so, because we have already penetrated into it deeply enough; but by freeing ourselves from the corporeal nature, we trace out the whole cosmos in the realm of spirit and soul, and the cosmos teaches us how the former earth life is connected with this life.
