The Threshold of the Spiritual World
GA 17
X. Concerning the Boundary between the Physical World and Supersensible Worlds
In order to understand the mutual relations of the various worlds, we must take into account the fact that a force which in one world is bound to develop activity in conformity with the order of the universe, may, when it comes to be developed in another world, be directed against that order. Therefore it is necessary for man's being that there should exist in his etheric body the two opposing forces, the capacity for transformation into other beings, and the strong ego-feeling, or feeling of self. Neither of these forces of the human soul can be unfolded in physical existence except in a deadened form. In the elemental world they exist in such a way as to make man's being possible by their mutual balance, just as sleep and the waking state make human life in the physical world possible. The relation of two such opposing forces can never be that of one effacing the other, but must be of such a kind that both are developed and act upon each other in the way of balance or compensation.
Now it is only in the elemental world that the ego-feeling and the capacity for transformation act upon each other in the way indicated; the physical world can only be worked upon, in conformity with the order of the universe, by the result of these two forces in their mutual relationship and cooperation. If the capacity for transformation which it is necessary for a person to possess in his etheric body were to extend in the same degree to physical existence, he would feel himself in his soul as something which in considering his physical body he is not. The physical body gives man in its own world a certain fixed stamp, by means of which he is put into that world as a particular personal being. He is not put into the elemental world with his etheric body in this manner. In the elemental world, in order to be a human being in the full sense, he must be able to assume the most varied forms. If this were impossible to him, he would be condemned to complete isolation in the elemental world; he would not be able to know about anything in it except himself; for he would not feel himself related to any other being or event. This, in the elemental world would be equivalent to the non-existence of those beings or events, as far as such a person was concerned.
If, however, the human soul were to develop in the physical world the capacity for transformation necessary for the elemental world, its personal identity would be lost. Such a soul would be living in contradiction with itself. In the physical world, the capacity for transformation must be a power at rest in the depths of the soul; a power which gives the soul its fundamental tone or keynote, but which does not come to development in that world.
Clairvoyant consciousness has therefore to live itself into the capacity for transformation; if it were not able to do this, it could make no observations in the elemental world. It thus acquires a faculty which it should only bring to bear so long as it knows itself to be in the elemental world, and which it must suppress as soon as it returns to the physical world. Clairvoyant consciousness must ever observe the boundary of the two worlds, and must not use in the physical world faculties adapted for a supersensible world. If the soul, knowing itself to be in the physical world, were to allow the capacity for transformation possessed by its etheric body to go on working, ordinary consciousness would become filled with conceptions which do not correspond to any being in the physical world. Confusion would reign in the life of the soul's thought. Observation of the boundary between the worlds is a necessary presupposition for the right working of clairvoyant consciousness. One who wants to acquire this consciousness must be careful that no disturbing element creeps into his ordinary consciousness through his knowledge of supersensible worlds.
If we learn to know the guardian of the threshold we know the state of our soul with regard to the physical world, and whether it is strong enough to banish from physical consciousness the forces and faculties, belonging to supersensible worlds, which should not be allowed to be active in ordinary consciousness. If the supersensible world is entered without the self-knowledge brought about by the guardian of the threshold, we may be overwhelmed by the experiences of that world. These experiences may thrust themselves into physical consciousness as illusive pictures. In that case they assume the character of sense-perceptions, and the necessary consequence is that the soul takes them for realities when they are not so. Rightly developed clairvoyance will never take the pictures of the elemental world for reality in the sense in which physical consciousness has to take the experiences of the physical world as realities. The pictures of the elemental world are only brought into their true association with the realities to which they correspond, by the soul's faculty of transformation.
Again, the second force necessary for the etheric body—the strong ego-feeling—should not be projected into the soul's life within the physical world in the same way as is appropriate for it in the elemental world. If it is, it then becomes a source of immoral propensities, as far as these are connected with egoism. It is at this point in its observation of the universe that spiritual science finds the origin of evil in human action. It would be misunderstanding the order of the world to surrender oneself to the belief that this order could be maintained without the forces which form the source of evil. If these forces were non-existent, the etheric being of man could not come to development in the elemental world. These forces are entirely good when they come into operation in the elemental world only. They bring about evil when they do not remain at rest in the depths of the soul, there regulating man's relation to the elemental world, but are transferred to the soul's experience within the physical world and are changed thereby into selfish impulses. In this case they work against the faculty of love and thus become the causes of immoral action.
If the strong ego-feeling passes from the etheric to the physical body, it not only effects a strengthening of egoism, but a weakening of the etheric body. Clairvoyant consciousness has to make the discovery that on entering the supersensible world, the necessary ego-feeling is weak in proportion as egoism in the experiences of the physical world is strong. Egoism does not make a human being strong in the depths of his soul, but weak. And when man passes through the gateway of death, the effect of the egoism which has been developed during the life between birth and death is such as to make the soul weak for the experiences of the supersensible world.
