20. How Does the Soul Find Its True Essence?

But even today, I may well make a comparison with regard to the attitude that animates the spiritual researcher, even when he sees a world of prejudices piling up against spiritual science. The spiritual researcher must think: There was a time when people looked up as far as their eyes could see; they saw the blue vault of heaven and, trusting their senses, they said: Up there is the vault of heaven, there is the moon, the stars, the sun, which wander back and forth across this vault of heaven. Then came Copernicus, came Giordano Bruno, standing alone before their contemporaries and proclaiming to them: What you believe you see with your eyes is not in space. This blue vault of heaven is the product of your limited vision; there is no boundary; the world extends into the infinity of space, and infinite worlds are embedded in these vast expanses. You yourselves create the firmament through the limitations of your knowledge.
