It has also happened that souls have incarnated and then left. There are many reasons why they go away. Children who die very young, after a few days or a few weeks―this may be for a similar reason. Most often it is said that the soul needed just a little experience to complete its formation, that it had it during these few weeks and then left. Everything is possible. And as many stories would be needed to tell the story of souls as are needed to tell the story of men. That is to say, they are innumerable and the instances are as different as possible from one another.
So, to decide arbitrarily: “It is like that, not like this; this is what happens and not that”, this is childishness. ''Everything''can happen. There are instances which occur more frequently than others, one can generalise, but one can never say, “This is not possible and it is always like this or always like that.” That is not how things happen. <ref>https://incarnateword.in/cwm/08/27-june-1956#p16,p17,p18,p20,p21,p22</ref>
''Can it happen that the psychic being does not fall at the place where it wanted to take birth?''
If a psychic being sees from its psychic world a light on the earth, it may rush down there without knowing exactly where it is. Everything is possible. But if the psychic being is very conscious, sufficiently conscious, it will seek the light of aspiration in a precise place, because of the culture, the education it will find there. This happens much more frequently than one believes, especially in somewhat educated circles. An intelligent woman with some artistic or philosophical culture, a beginning of conscious individuality, may aspire that the child she is going to have may be the best possible according to her idea or according to what she has read. Hence it is not so very complicated to find a place. The number of psychic beings born constantly being considerable, if each time exceptional conditions have to be found it would be difficult. Surely, there are instances where the psychic beings seems to have fallen headlong and been stunned, but this is bad luck; in such a case it generally requires a long time to wakeup. It is bad luck in the sense that it probably lacked a certain power of discrimination, or perhaps it had to face certain forces which thwarted its decision and won a partial victory over it. There are a thousand possibilities, you know. One cannot say that everything goes according to the same plan—every psychic being is different.
''When great souls want to be born upon earth, do they choose their parents?'' Ah! that depends on their state of consciousness, it depends on the state of their psychic formation. If the psychic being is completely formed, if it has reached the perfection of its being and is free to reincarnate or not, it has also the capacity of choosing… They don’t have a physical sight like ours so long as they are not in a body. So, evidently, they look for a body which is adapted and fit to express them, but they must give its share to the material inconscience, if it may be put thus, and to the necessity to adapt themselves to the most material laws of the body. So, from the point of view of the psychic, the choice of the place where one is born is important, it is more than an insignificant detail. But there are so many things that can’t be foreseen. For instance, one chooses an environment, a country, a certain type of family, one tries to see the nature of the likely parents, one asks for certain already well-developed qualities in them and a sufficient self-mastery. But all this is not enough if one does not carry in oneself a sufficient dynamism to overcome the obstacles. So, all things considered, this is not enormously important. Anyhow, even at the best, even if the parents have collaborated consciously, there is an enormous mass of the subconscient and the yet lower inconscient which from time to time rises again to the surface, gets stirred up, damages the work, makes calmness and silence indispensable. Always, always a preparation is needed, even if one has chosen—a long preparation. Not to speak of the phenomenon of being half-stunned at the moment of birth, the descent into the body, which often lasts for a very long time before one can escape from it completely. <ref>https://incarnateword.in/cwm/05/30-december-1953#p9,p10</ref >
...it [choice to choose its place of birth in next life]depends absolutely on the condition in which they died and their last wish, and on the resolution of the psychic. It is not a mechanical or imposed thing, it is different for each one.
