On the Golem
“The life force of the golem is the Hebrew alphabet, the secret name of God inserted under his tongue, or the word “truth,” one of God’s names, engraved on his forehead. (When the first Hebrew letter of “truth” is erased it becomes “dead.”) The legend of the golem conformed to, and strengthened, the image of the kabbalah as a doctrine that could bring great benefits, but one that also includes some sinister, dangerous elements.”
