I. The Spirit-Seed of Man's Physical Organism. Walking, Speaking and Thinking, and Their Correspondences in the Spiritual World

Think of the Earth with the air around it; farther outward is the cosmic ether, gradually passing over into the spiritual sphere. Here on the Earth we inhale and exhale the air. This is the rhythm of breathing. But out yonder we pour our being into the Cosmos, receiving into ourselves the Logos and the Cosmic Thoughts. There we let the World, the Universe, speak in us. This too takes place in rhythm—in a rhythm determined by the world of the stars. Out in the Cosmos there is also rhythm. As human beings on the Earth we have the rhythm of breathing, which is related in a definite way to the rhythm of blood-circulation: four pulse-beats to one breath. In yonder world, we breathe out and breathe in again spiritually; this is cosmic rhythm. As men on Earth our life depends upon the fact that we take a definite number of breaths a minute and have a definite number of pulse-beats a minute. Out in the Universe we live in a cosmic rhythm, in that we breathe in, as it were, the moral-ethereal world; we are then within ourselves. And when we breathe it out again we are united with the Beings of the Higher Hierarchies.
