“Jewish Devilry” is a book about evil spirits in the Jewish tradition and in the popular perception. The attitude to this side of the world is another mirror in which one can better discern and understand the character of the nation. Jewish devils are no match for all foreign demons, large and small demons. They have a more luxurious family tree, and a higher purpose, and their behavior is more original. Impure power is mysterious and unpredictable for ordinary human understanding, but it fits perfectly into the picture of the world pre-established by the Creator and knows its place in it. She can do bad things to people, and maybe even help them – if you obey the wise men and know how to behave with her. The author of the book talks about all this with enthusiasm and infectiousness, combining erudition with humor, the Talmudic culture of discussion with the folk culture of laughter, piety with a salty anecdote.
