The seal of alchemy is knowledge hidden in a symbol.
Alchemists used symbols to store deep or ancient knowledge so that it could only be interpreted by those who knew how to use it.
This geometric symbol which represents the fifth element or quintessence, that is the basic material of creation, is also called the Hermetic symbol and used by alchemists to describe the process of creation.
Accordingly, the symbol means that emptiness (the small circle) activated by thought (the rectangle) and purified / refined by universal consciousness (the triangle), leads to manifestation (the large circle).
The hidden statement is: "that which is everything manifests the world with that which is nothingness (potential energy)."
And the hidden message in all this is "mind creates reality."
