VII. Inner Processes in the Human Organism. Sense-Perception, Breathing, Sleeping, Waking, Memory

I want you to grasp in its full significance what I am now going to say. If you have some kind of gas in a closed vessel, you can compress this gas so that it becomes denser. That is a process in Space. But it can be compared—naturally only compared—with what I have just been describing to you. You go back in your astral body and your ego to the morning of December 22nd, and then, when you next wake, you jerk quickly forward to the morning of December 23rd. You impel your soul forward in Time. And through this process your soul-being, your astral body, becomes so condensed within Time, that it carries the impressions of the outer world not only for a short period, but as enduring memory. Just as any gas that is condensed exercises a stronger pressure, has more inner power, so does your astral body acquire the strong power of remembrance, of memory, through this inner condensation in Time.
