This spell I got from Elf Realm: The Low Road by Daniel Kirk.
It will disable a machine.
Casting Directions for ‘Disable a Machine’
Circle round the machine at midnight and hold hands. The eader says, I, (name of leader), Mage of (name of city), Mistress of the portents of Good, which are as the trunk and branches of my Soul, have turned toward thee. How I have established thee! How my grateful tear have nourished your origins. How highly I’ve sung your praises! In the name of the mulberry, the beech, and the tulip, in the title of the locust, ash, and witchslazel, in the name of the hemlock, larch, and box elder, in the title of the pine, the walnut, and the walnut, may you heed my cry! In the name of their eyes, the ears, the heart, the tongue, and body, may yhu deal graciously with me.
Great spirits of heaven and earth that I beseech thee, All praises be sung in thy name, May you reside in our center with the strength of the sun, In a glittering halo of fire. We bow to your wisdom, and pray you may grant The fulfillment our sole desire, And yield command of the transmuting fire, Your unquenchable cauldron of passion. May you grant us one orb of devouring heat, An inferno whose radiance you feed, And accelerate the white-hot combustion inside, Like the life force that awakens in a seed. May this spark be exalted in pure incandescence, May you give us one power this night, May you lift up the veil of your luminous world In one searing pinpoint of light.
Everyone chants, bring down, bring down, one coal from your furnace over and over until a white-hot ball of fire to hover in the atmosphere. When you do, softly chant, Close this window, enlighten this passion, Unyoke its power in desire To place such might in our hands, And return to our demands.When it combusts on the taxi, you are done. Problem solved!
