The wind carried it in its womb; the earth is the nurse thereof.
It is the father of all works of wonder throughout the whole world.
The power thereof is perfect, if it be cast on to earth.
It will separate the element of earth from that of fire, the subtle from the gross, gently and with great sagacity.
It doth ascend from earth to heaven.
Again it doth descend to earth, and uniteth in itself the force from things superior and things inferior.
Tabula Smaragdina, 4 – 8
