Magic Squares have the property of symmetric resolution. By their nature, they form a completed pattern. The fact that every row, column, and diagonal of the figure adds up to the same total, gives them balance. The universe as a whole is a system in which we draw forth balance and completion. The very cycle of Life is seen as a never-ending circle, a continuing pattern which is repeated over and over; A Magic Square models this pattern.
Magic Squares, also give us endless repetition. We can add each row and column in turn, and arrive at the same result over and over. This is the very nature of spells; a charm or prayer which is repeated over and over to build momentum, and draw power for a working.
