I have touched on all of this only because in reality it lifts a first little corner of the veil covering the process that people call "death", a process that very often terrifies them. But the human being has no reasons to be afraid of death other than those created by itself. And through spiritual science the modern seeker has the possibility of becoming familiar with what happens during the process of death, so that anxiety and uncertainty can be overcome and replaced by confidence and peace of mind. It is quite true that after the process of death with which people are familiar only the discarded physical body or corpse remains. One is not able to see the being appear in a new form. But is this an irrefutable proof that the consciousness is wiped out when the organism decomposes? No – we can physically experience another person's consciousness only when this other person has a physical body through which to manifest himself, just as we can experience radio waves only when there is a radio through which they are transformed into sound waves.
      Yet we are in no doubt that radio waves exist, even though we cannot hear them. The consciousness or mentality of the living being is also a reality that exists in the form of rays or waves. These energies cause the complete renewal of life and the transformation of the organism, both where it occurs in various stages as is the case with the insects mentioned above, and where a gradual, almost imperceptible transformation takes place as in the case of the terrestrial human being. And if one compares the replacement of the organism of the insects mentioned above and the replacement of the organism in that species of beings to which terrestrial human beings belong, does one not have a proof that this ability to replace the organism is, like all other abilities, subject to evolution? The ability of the terrestrial human being to replace its organism is in reality far more developed than that of the insects.
      To be able to replace one's organism quite imperceptibly as the terrestrial human being does in one physical incarnation, through the stages of childhood, youth, maturity and old age, without having to interrupt the functioning of its day-consciousness, and to be able to have the feeling that it is still the same organism without this really being the case, is something of an ideal in relation to the stage of evolution where the beings have to go through a kind of death process several times in one incarnation.
      The terrestrial human being has reached a step in evolution where it is free from that kind of unpleasant interruption in the transformation of the organism until its earthly life, through ill-health, accident or the natural wear and tear of old age, is interrupted and its consciousness is carried by spiritual or ray-formed bodies, those that carry the consciousness during sleep. But when a way of replacing organisms more primitive than that of human beings exists, is it not just as natural for there also to exist a way that makes the human beings way seem primitive, but which they can gradually learn to avail themselves of? This means a replacement of the organism where the process we call "death" can also be changed into a gradual process of transformation instead of an abrupt transition from one state to another. And therefore the "horror of death" will be overcome, and there will be no more shock associated with this process of transformation, which can be the case for people now who, with their physical eyes, see the physical bodies of other people become corpses without being able, with the same eyes, to see the same people in the bodies formed of rays that now carry their consciousness.
