Descriptions of inner, spiritual processes are much more liable to misunderstanding than descriptions of events in the physical world. Such misunderstandings arise easily because the life of the soul is in constant movement and because we fail to bear in mind that the life of the soul is very different from life in the physical world.
Acquaintance with the human kingdom is limited: between death and a new birth - and this begins immediately or soon after death - the soul has contact and can make links only with those human souls, whether still living on earth or in yonder world, with whom he has already been karmically connected on earth in the last or in an earlier incarnation.
However superficial prevailing views of heredity seem to be, it must be admitted that a person is indeed the bearer of inherited characteristics. This is the one aspect. He must often battle against these inherited traits and rid himself of them in order to bring to fulfillment the talents laid into him before he entered earthly existence.
It is the forces of the universe that make human beings fall ill. Having learnt to recognize how sun qualities and moon qualities live in plants, animals and minerals, we discover how we can find counterforces and also individual natural forces that point us towards medicines for specific internal illnesses.
By giving material expression to force-forms in space, the Greeks gave divine spiritual beings the opportunity of using these material forms. It is no figure of speech but a fact when we say that gods came down at that time into the Greek temples in order to be among human beings on the physical plane.
In order to find our bearings in the spiritual worlds and see truly what is there for us to see, we need a further inner trait in our character, a quality I should like to term 'presence of mind.' In ordinary life, this is the trait we need when faced with a situation that requires us to make an immediate decision without hesitation.
Architecture produces a musical mood in our inner being, and we notice that even though the elements of architecture and music appear to be so alien in the outer world, through this musical mood engendered in us, our experience of architecture brings about a reconciliation, a balance between these two elements.
If spiritual science is to do the same for spirit that natural science has done for nature, it must investigate quite differently from the latter. It must find ways and means of penetrating into the sphere of the spiritual, a domain which cannot be perceived with outer physical senses nor apprehended with the intellect which is bound to the brain.
In the life of our organism, we are continually dealing with a development of force followed by a state of equilibrium. Of course, the human being has no conscious knowledge of what is really going on within him, but what takes place is so infinitely wise that the cleverness of the human ego is nothing by comparison.
