Let the televisors of this ship, which are its eyes, become blind. Let its grapples, which are its arms, be paralyzed. Let the nuclear blasts, which are its fists, lose their function. Let the motors, which are its heart, cease to beat. Let the communications, which are its voice, become dumb. Let its ventilations, which are its breath, fade. Let its lights, which are its soul, shrivel into nothing. In the name of the Galactic Spirit, I so curse this ship." And
