If I'm not mistaken, Gematria is Kabbalah, correct? And numerology is in the same vein as subjects such as astrology. I can't force you to do anything but I'd definitely urge you to leave it behind. Anything related to the occult (including Kabbalah and astrology) is playing with literal fire, and I'm not just talking about eternal damnation here: the invitation of dark forces into your physical life is a recipe for disaster.
Again, I can't force you to stop but I highly urge against all occultism.
