Judaism *is* Gnosticism. All the Kabbalah nonsense, the madness of the Zohar, and the perversion of the Talmud are derived from Babylonian and Egyptian Gnostic "secrets".
Or you could simply not involve yourself with demons. There is no "knowledge" they want to share that's worth having, half the time its literal retardation like "there are 42069 genders". Your better off going to the local nature center and watching the animals, they can teach you a lot more.
