Calling on the Name of the Lord Jesus Christ - our Savior - we will try to do this work, where we will not only begin to learn how to turn the worst metal into the best - iron into copper, copper in silver, and silver in gold, and so on, but also cures all diseases whose treatment is biased and arrogant doctors seem impossible, and even more so to help mortals maintain their health to a deep and perfect age. This art was inscribed by the Lord God, the Almighty Creator, from the beginning of creation, as if in a book, into the bodies of metals. And some of them we need to study this art carefully. Therefore, when one wants to master this art zealously and completely from its true foundation, it will be necessary for him to learn from the Master, that is, from God who created all things, and the only one knows what nature and property he stated. in every creation. Therefore, He can teach all indisputably and perfectly, and from Him we can learn, for He said, "By Me you will know all things." After all, one cannot find such secrets in heaven or on earth, of which He has the qualities, which created everything, does not understand, does not know and does not see the most accurate. We will therefore accept Him as our mentor, leader and leader in this true art. Therefore, we will follow Him alone, and through Him we will learn and gain knowledge that He Himself engraved with His finger in the bodies of metals. And it so happens that the Almighty Lord God blesses all the creations for us and all our paths, so that in labor we can lead our house to the desired end and as a result can produce extraordinary joy and love in our hearts. But if one follows only his own understanding, he will lead not only himself but also all the others who have accepted this opinion into great sin and lead to their harm. For man is, of course, born in ignorance, so that he can know or understand nothing himself, except what he receives from God and understands from nature. Anyone who learns nothing from them is similar to pagan teachers and philosophers, and follows the subtleties and art of personal inventions and opinions - such as Aristotle, Hippocrates, Avicenna, Galen, etc., who based their art only on their own opinions. . And if they ever learned anything from nature, they destroyed it with their fantasies, dreams, or inventions before they fully understood anything; so that neither they nor their followers find anything perfect.
