Numbers hold power. As mentioned above under the Formulae entry, that power can be unlocked through arcane mathematics. Sometimes, though, all you need is a single number – nine, for example – to seal your mystical intentions.

On a related note, the occult practice of numerology draws connections between specific numbers and the deeper levels of Creation. As such, it provides a venerable focus for Correspondence, Spirit, Prime, or Time Arts, acting as a tool for understanding the ties between one thing and another. And so, beyond the baroque patterns of number theory, simple numbers or numerical correspondences (Bible verses, racing horses, sports-team player numbers, etc.) can be remarkably potent tools when they get assigned to something you’re trying to accomplish.
