Separate the Earth from Fire, the Subtle from the Gross, gently and with great Ingenuity. It rises from Earth to heaven and descends again to Earth, thereby combining within Itself the powers of both the Above and the Below.
Thus will you obtain the Glory of the Whole Universe. All Obscurity will be clear to you. This is the greatest Force of all powers, because it overcomes every Subtle thing and penetrates every Solid thing.
~ Thoth
