The magic square when tied to alphanumeric letters provides names associated with the powers of the enumerator. It is a synthesis of numerology, language as magic, and spacetime. Each square is a micro-power and when the square is moved around it provides access to locations in space-time using the numbers as unifying principles of the powers associated with them. When we make sigils, vocalize with them, calculate names and words of power, or use gematra/abjad to explore each individual cell in the squares meeting we end up extrapolating a type of relational power between what the pythagoreans and plato considered to be the most universal and idealized forms in the world of forms. If you know advanced magic or advanced mysticism you can practically apply them by using the names as vocalized daisy chains of micro-spells or visualize/meditate on their sequences/formulas using the holy scripts. This can generate visions, magic, spirits, and powers for the mystic or magician.
Magic squares are high level magic for the most disciplined, learned, and practiced. they are a requirement to get to a level of magic where you're communicating with the cosmos vs "pls gimme gf/money mr demon pls". They have the ability to reach through time itself and grant you access to any location in it.
