Links are formed karmically on the earth and then continue between death and a new birth. Those who are able to see into the spiritual world perceive how the dead person gradually makes more and more links - all of which are the outcome of karmic connections formed on earth.
All things which have a directing force here in the physical world cease to exist when one arrives in the imaginative world. If, on the physical plane, you imagine yourself to have done something you actually have not done, you will soon be persuaded by the facts of the physical world that this is not so. This is not the case in astral space.
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.
We know even from ordinary life that we have to achieve a sufficient degree of attentiveness if we want to concentrate on an inner picture or an object of some kind; we must also have it in our power, though, to turn our soul away from something we have been concentrating on.
If you observe children with sufficient objectivity as they grow into the world, then you will perceive that children's temporal bodies are still not fully connected with the spirit-soul. The task of education, understood in a spiritual sense, is to bring the soul-spirit into harmony with the temporal body.
Anyone who believes that it is possible to educate the will without cultivating the insight that enlivens it is succumbing to illusion. Clear-sightedness on this point is a task for present-day pedagogy, but it can come only from a life-filled understanding of the whole human being.
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.
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.
In raising children, we need to continuously keep in mind how we can best create the most favorable environment for their imitative behavior. Everything done in the past regarding imitation must become more and more conscious and more and more consciously connected with the future.
What is of the nature of spirit and soul must be gleaned from facts belonging to the spirit and soul; we shall then know that in the living thinking which is liberated from the will, a life-germ has been discerned which passes through the gate of death, goes through the spiritual world after death, and afterwards returns again to earthly life.
