Raymond Lulle says, that to make gold, one must have gold and mercury; and to make silver, silver and mercury. And he adds: "I mean by mercury, that mineral spirit so fine and pure that it gilds even the seed of gold, and silvers that of silver." He meant by this, either electricity, or Od, the astral light.

The Salt and Sulphur serve in the work only to prepare the mercury, and it is to the mercury especially that we must assimilate, and, as it were, incorporate with it, the magnetic agent. Paracelsus, Lulle, and Flamel alone seem to have perfectly known this mystery.

The Great Work of Hermes is, therefore, an operation essentially magical, and the highest of all, for it supposes the Absolute in Science and in Will. There is light in gold, gold in light, and light in all things.

The disciples of Hermes, before promising their adepts the elixir of long life or the powder of projection, advised them to seek for the Philosophal Stone.

The Ancients adored the Sun, under the form of a black Stone, called
Elagabalus, or Heliogabalus. The faithful are promised, in the
Apocalypse, a white Stone.

This Stone, says the Masters in Alchemy, is the true Salt of the philosophers, which enters as one-third into the composition of Azoth. But Azoth is, as we know, the name of the grand Hermetic Agent, and the true philosophical Agent: wherefore they represent their Salt under the form of a cubical Stone.

The Philosophal Stone is the foundation of the Absolute philosophy, the Supreme and unalterable Reason. Before thinking of the Metallic work, we must be firmly fixed on the Absolute principles of Wisdom; we must be in possession of this Reason, which is the touchstone of Truth. A man who is the slave of prejudices will never become the King of Nature and the Master of transmutations. The Philosophal Stone, therefore, is necessary above all things. How shall it be found? Hermes tells us, in his "Table of Emerald," we must separate the subtile from the fixed, with great care and extreme attention. So we ought to separate our certainties from our beliefs, and make perfectly distinct the respective domains of science and faith; and to comprehend that we do not know the things we believe, nor believe anything that we come to know; and that thus the essence of the things of Faith are the unknown and indefinite, while it is precisely the contrary with the things of Science. Whence we shall conclude, that Science rests on reason and experience, and Faith has for its bases sentiment and reason.

The Sun and Moon of the Alchemists concur in perfecting and giving stability to the Philosophal Stone. They correspond to the two columns of the Temple, Jachin and Boaz. The Sun is the hieroglyphical sign of Truth, because it is the source of Light; and the rough Stone is the symbol of Stability. Hence the Mediæval Alchemists indicated the Philosophal Stone as the first means of making the philosophical gold, that is to say, of transforming all the vital powers figured by the six metals into Sun, that is, into Truth and Light; which is the first and indispensable operation of the Great Work, which leads to the secondary adaptation, and enables the creators of the spiritual and living gold, the possessors of the true philosophical Salt, Mercury, and Sulphur, to discover, by the analogies of Nature, the natural and palpable gold.

To find the Philosophal Stone, is to have discovered the Absolute, as all the Masters say. But the Absolute is that which admits of no errors, is the Fixed from the Volatile, is the Law of the Imagination, is the very necessity of Being, is the immutable Law of Reason and Truth. The Absolute is that which IS.

To find the Absolute in the Infinite, in the Indefinite, and in the
Finite, this is the Magnum Opus, the Great Work of the Sages, which
Hermes called the Work of the Sun.
