"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)
