VI. Spiritual Insight Offering Greatest Liberation II: The Mission of the Spiritual Science Movement
It is not too easy, however, to read like this. To give you an example, let me tell you the following. A chemist may take blood, analyse it and say it consists of such and such constituents. He has now done his job and he knows what blood is. Reading in the spiritual scientific and occult sense, however, you find that blood could not have come into existence in the form in which we have it if there were not the phenomena behind it which we call astral phenomena. The spirit of the world acts on matter through the astral phenomena. There could never have been such a thing as blood in the physical world if the astral world did not exist behind the physical world. All kinds of things could exist, but blood is only possible because there is the astral world behind it. You thus read the astral in the blood, just as you read the world ‘spirit’ in these letters. Reading the letters that exist here in the physical world leads to perception of the astral sphere.
