A must for anyone seeking to understand the Jewish gnosis and metaphysics

Very interesting book. The only weak point in my opinion is that it does not show sufficiently how the Jewish gnosis (Cabala monistic, messianic Kabbalah, Kabbalah dualistic) was inspired by the Christian gnosis or not, including its developments in the more outrageous as the "redemption through sin" salvation or redemption by crime and perversity. Anyone who knows a little history of Gnosticism Gnostics know that the Jews did not invent anything. At best they have reinvented the worst they pumped!
