"It does not exist in Nature, but has to be prepared by Art, in obedience to Nature's law. Its substance is in metals;
but in form it differs widely from them, and in this sense the metals are not our Stone. (...) The specific properties of the metal have their abode in its spiritual part, which resides in
homogeneous water. Thus we must destroy the particular form of gold, and
change it into its generic homogeneous water, in which the spirit of gold
is preserved; this spirit afterwards restores the consistency of its water, and
brings forth a new form (after the necessary putrefaction), a thousand times more perfect than the form of gold which it lost by being reincrudated."

out of cold and humid Mercury
by assiduous digestion;"
"It is that one true, natural, first-substance, to which
nothing is added, from which nothing is subtracted, except certain superfluities, which, however, it will cast off without any aid by its own inherent vital action"
