19.  The  union  and affection that  exist between family members are an  indication of a  former sympathy21  that  has brought them together. One also says of someone whose character, tastes, and  inclinations have no  similarity to  those of  their closest relatives, that he or she is not of that family. Saying this declares a greater truth than one might suppose. God allows such incarnations of antipathetic or foreign spirits within families with the dual objective of serving as a trial for some and as a means of advancement for others. The evil ones better themselves little by little through contact with the good ones and the care they receive from them. Their character becomes milder, their habits more purified and antipathies are erased. It is thus that the fusion amongst different categories of spirits is established, as occurs on the earth amongst ethnicities and cultures.20. The fear of the unending increasing of kinship as a consequence of reincarnation  is a selfish fear, which demonstrates that one does not feel a sufficiently broad love to carry it over to a large number of individuals. Does a father who has many children love them all any less than he would if he had only one? But selfish people may rest at ease because such fear is without foundation. From the fact that one man has had ten incarnations it does not follow that in the spirit world he will encounter ten fathers, ten mothers, ten wives and a proportional number of children and new relatives. There he will always re-encounter only the same objects of his affection, those who had been connected with him while on earth under various relationships, or perhaps even the same ones.
