27. In order that man shall be happy upon the Earth, it is necessary that it be peopled with good spirits, incarnate or discarnate, who desire only good. This time has arrived; a great emigration is being accomplished at this moment among those who inhabit it. Those who return evil for evil, and in whom the desire to do right is not felt, being unworthy of the transformed state of the Earth, will be banished from it, because they will bring only trouble and confusion, and would be an obstacle to progress. They will go to expiate their hardness of heart, some into inferior worlds, and others with terrestrial races behind them in development, which will be the equivalent of inferior worlds, where they will carry their acquired knowledge, and where it will be their mission to teach undeveloped beings this knowledge. They will be replaced by better spirits, who will make justice, peace, and fraternity rule among them.
The Earth, according to the intelligence gained from the spirits, must not be transformed by a cataclysm which would suddenly annihilate a generation. The present generation will gradually disappear, and the new one succeed in the same manner without anything having been changed in the natural order of things.
All externally will pass along as is usual, with this difference alone, which is an important one, that a part of the spirits which are incarnated here now will no more be incarnated here. The children who will then be born, instead of being underdeveloped and inclined to evil, will be more advanced spirits inclined towards righteousness.
It acts then much less upon a new corporeal generation than upon the new generation of spirits. It is undoubtedly within this context that Jesus understood things when he said: “I tell you the truth, this generation will certainly not pass away until all these things have happened.” Thus, those who will expect to see the transformation brought about by supernatural or miraculous effects will be disappointed.
