Mounpus* saith: Know, all ye investigators of this Art, that the head is all things, which if it hath not, all that it imposes profits nothing. Accordingly, the Masters have said that what is perfected is one, and a diversity of natures does not improve that thing, but one and a suitable nature, which it behoves you to rule carefully, for by ignorance of ruling some have erred. Do not heed, therefore, the plurality of these compositions, nor those things which the philosophers have enumerated in their books. For the nature of truth is one, and the followers of Nature have termed it thdt one thing in the belly whereof is concealed the natural arcanum. This arcanum is neither seen nor known except by the Wise. He, therefore, who knows how to extract its complexion and rules equably, for him shall a nature rise forth therefrom which shall conquer all natures, and then shall that word be fulfilled which was written by the Masters, namely, that Nature rejoices in Nature, Nature overcomes Nature, and Nature contains Nature; at the same time there are not many or diverse Natures, but one having in itself its own natures and properties, by which it prevails over other things. Do you not see that the Master has begun with one and finished one? Hence has he called those unities Sulphureous Water, conquering all Nature.
