During the Middle Ages, passages from the Sefer Yetzirah (Book of Creation) were studied as a means to attain the mystical ability to create and animate a golem, although there is little in the writings of Jewish mysticism that supports this belief. It was believed that golems could be activated by an ecstatic experience induced by the ritualistic use of various letters of the Hebrew Alphabet.
