Therefore, Make the earth black;
separate the soul and the water
thereof, afterwards whiten;
so shall ye find what ye seek.
I say unto you that whoso makes earth black
and then dissolves with fire, till it becomes even
like unto a naked sword, who also fixes
the whole with consuming fire, deserves
to be called happy, and shall be exalted
above the circle of the world.
