"I will make this known to thee in all truth [for the love of God], that the root of philosophic sulphur, which is a heavenly spirit, is united in the same material with the root of the spiritual and supernatural mercury, and the principle of spiritual salt—out of which is made the Stone, and not out of several things. That universal thing, the greatest treasure of earthly wisdom, is one thing, and the principles of three things are found in one, which has power to change all metals into one. The three things are the true spirit of mercury, and the soul of sulphur, united to spiritual salt, and dwelling in one body; they are dragon and eagle, king and lion, spirit and body, etc.” - Basilius Valentinus (Lib. Nat. et Supernal., c. 4)
"The Sign of the Center of Nature is the Tincture, the Essence and the Oil; Mercury, Sulphur, Salt: the Way to the glory of the age.”
"All things (man included) are composed out of three substances, and all things have their number, their weight, and their measure. Health exists when the three substances constituting a thing preserve their normal proportion of quantity and quality; disease results if this proportion becomes abnormal. These three substances are called Sulphur, Mercury, and Salt."
— "Life of Paracelsus" by Franz Hartmann
