Let me remind you once again that you were all clairvoyant in earlier times. Why is it that you no longer possess the faculty of clairvoyance? It is because in former times you were not bound to the earth’s existence, because you were remote, in spiritual worlds; you did not bring the spiritual world down into your faculties; your visionary clairvoyance was based upon the condition of being remote from the physical world.
This must be clear to us. We must inscribe these fine shades of thought upon our minds and souls; we must be clear that the task of a real occult science to-day is to impart those results of spiritual investigation which are permeated with a thinking content, so that one can always clothe the results of spiritual research in such a way as to be comprehensible through thinking to the man who is not clairvoyant. To this end they must first be combined with thought.
