linballina, gärna prata lite eller allt detta för ditt svar, men jag vill att den är närvarande för efterlevans skull. Detta är " Dybbuk av Mazel Tov IV " av Robert Silverberg
Här är text från en recension :
The planet known as New Israel, or Mazel Tov IV, was colonized by two groups of Jews (reformed and Hasidic) fleeing certain destruction on Earth. They coexist with the centaur-like natives peacefully for many years until something unexplainable happens: the spirit of a dead Jew appears in the body of a native, much like the dybbuk of Jewish folklore. The natives are not terribly surprised—this sort of thing happens to them from time to time—but their exorcism ceremony doesn't work this time. The Hasidim come to the rescue, however, and the ceremony is so successful that the natives want to convert. One of Silverberg's religious-themed stories, this one quite amusing, though not critical or condescending to any parties concerned. Also note that no effort is made to explain the possession scientifically.
