>The Tanya's hypotheses that every Jew has two souls and that the souls of non-Jews are fundamentally different from those of Jews (with non-Jewish souls originating from the realm of evil) More precisely, the Tanya states that Jewish people have two souls: the nefesh elokis (or divine soul) and the nefesh behamis (or animal soul) It states that non-Jews have only the latter.
