The core of gematria and number magic is to create sympathetic reactions to things that are based on numerical values. Let’s say someone’s name sums to 666, and they are killed 66 days after their 66th birthday. There is actually no significance to this event other than it being triggered to make schizos believe it. These rumblings then affect the entirety of the nation by changing even the slightest tones of how they are reported. So even simpler; magic doesn’t exist, they are preplanned events to make people who are magic aware think magic is occurring. It’s dead simple.
