The Emerald Tablet of Hermes
Tabula Smaragdina
The Emerald Tablet is thirteen sentences long. In those thirteen sentences it claims to contain the secret of the whole world. “As above, so below” is its most famous line — the basis of the Hermetic principle that the macrocosm and microcosm mirror each other, that the structure of the universe is reflected in the structure of the human soul, that to understand one is to understand the other.
