Lecture I
We know that the oxygen of the air circulates through our organism in a comparatively short time. We count these cycles by the pulse-beat. This happens quickly. The people of whom I am now speaking did indeed imagine the receiving of thoughts as a kind of breathing, but it was a very slow breathing. It consisted in this: At the beginning of his earthly life, man becomes capable of receiving the thoughts. As we hold the breath within us for a certain time—between our in-breathing and out-breathing—so did those people conceive a certain fact, as follows: They imagined that they held the thoughts within them, yet only in the sense in which we hold the oxygen which belongs to the outer air. They imagined that they held the thoughts during the time of their earthly life, and breathed them out again—out into the cosmic spaces—when they passed through the gate of death.
