II. The Elemental Kingdoms of Nature

We can understand such things in the best way, if we proceed from what we can perceive through our senses—from the kingdoms of the sense-world, which are accessible to human observation. Here, in the physical sense-world, four kingdoms are spread out before our senses: the mineral kingdom, the plant kingdom, the animal kingdom, and the kingdom of man. This is common knowledge. Let us now try to form some clear idea as to the precise nature of these four kingdoms; for this is by no means clear to everyone. And for this same reason, it is also not so easy to gain an insight into the first, second and third elemental kingdoms. It is precisely when we speak of such difficult matters, that we must take great care, from the very outset, to realize that no true goal can be reached, if we believe that a concept which we have, as it were, driven like a stake into the ground, once formed it can be left rooted in this place. This may still be possible within the physical sense-world, for here, things stand one beside another; there is a division between them, just as this book, this piece of chalk, a rose, etc., are distinct and separate from one another. It is possible, in this case, to apply a term to a single object, for when we have named something, we can be sure that we have before us something distinct and limited. If, however, we went to the astral plane, that world which is immediately beyond our own, and permeates it, as the one nearest to it, we find that this no longer holds true, for the astral world is one of eternal movement. If you observe the astral body of man, which floats around him as his aura and is the expression of his desires and passions, etc., you will see that this astral body of man is in a constant motion—it is an ebb and flow fall of colours and forms, which change at every moment, for new colours shine forth and others disappear. This is what we find in the case of man. But there are other Beings which whirl about on the astral plane. Their astral bodies do not form part of a physical body, although they are no less changeable and variable, for at every moment they have a different shape, colour, or luminous force. Everything on the astral plane is the continual expression of the inner nature of these Beings. We would, indeed, find ourselves in a difficult position if we were to apply to the astral plane the rigid, unchangeable concepts of the physical world. We must learn instead to adapt ourselves to the mobility of these shapes—we must acquire mobile concepts. We should be able to use a concept, once in this way, and once in that.
