You must determine which type of energy is needed to fulfill the need. Thus, if money is needed, you could access from the Fe Rune, which is the force behind wealth. You may choose to align with Elemental Earth, as finance is one of its myriad attributes. You could also invoke any of the deities whose province includes bestowing wealth and good fortune. The most popular types of spells are those devoted to love, money, success and protection.
Love spells are particularly tricky.
One may cast a spell to attract a lover, but may not cast a spell on a specific individual to make that person fall in love with the spellcaster. To attract a lover, for example, a pink candle may be inscribed with the Ing, Gyfu and Bjork Runes. The stone is then charged to add to the spell. When the candle is finished, the stone is secreted among personal belongings. A money spell requires inscribing three Fe Runes on a twig.
