18. Family ties are not destroyed through reincarnation as some would believe. On the contrary, they become stronger and closer. The opposite principle would, on the other hand, certainly destroy them.
In space, Spirit entities form groups or families bound together by affection, sympathy towards each other, and by similar inclinations. Happy at being together, these Spirits seek each other. Incarnate life separates them only for a while, so on returning to the spiritual world they again reunite as friends who have just returned from a journey. Frequently they will even follow each other into the incarnate form, coming here to be united in the same family or the same circle of friends and acquaintances, in order to work together for their mutual progress. When some members of the same spiritual family become incarnate and others not, they then continue their contact by means of thought. Those who are free watch over those who are captive. Those who are more advanced do everything they can for the less advanced, so helping them to progress. After each physical existence all have made some advancement, even if it is only a step along the path to progress. As they become less bound by matter, their affections become more real and more spiritually refined, due to the fact that they are not perturbed by selfish or violent passions. This then allows them to live many lives in the flesh without suffering any loss of mutual esteem.
It is understood, of course, that we refer to real affection, soul to soul, being the only love which survives after the destruction of the body. So it follows that those of this world who join together because of physical attraction, will have no motive to look for each other in the spirit world. The only lasting relationships are those linked by spiritual affection, all carnal affections being extinguished together with the cause that brought them about, in other words, the physical body. Understand by this that the physical cause no longer exists in the world of Spirits, but the soul exists eternally.
With regard to those who join together exclusively out of interest, they clearly mean nothing to each other. Death separates them both on Earth and in Heaven.
