That seems to be reinventing the wheel. Why not experiment with a magical system thousands of years old? See, a spell is a formula. An analogy is like its a road to a destination. Would you rather whack your way through the underbrush, or ride down a path that others have already proven to work? This is the difference between subjectivity and objectivity. If a spell or a divination practice works for you but not for someone else, its entirely subjective. If it works for anyone, it is objective, and therefore valuable knowledge to have. Additionally, there is more energy expended in 'casting' a newly formulated spell than there is expended in 'casting' a proven spell that others have used before. And, I disagree that a spell requires a deity.
