I'm pretty lousy at noticing/interpreting symbolism in fiction, in case that would either help or hurt my enjoyment here (e.g. "blowing right past symbolism that I wouldn't understand anyway" might be better than "noticing it but being stumped for lack of religious background").
As someone who skews atheist but is fascinated by religion, the Kabbalistic mysticism was not only fascinating in its own right, but also a superb lens to examine theological questions without triggering the reflexive aversions many of us non-believers have developed w/r/t Christianity.
