Since, Basil Valentine, by Religious Vows am bound according to the Order of St. Benedict, and that requires another manner of Spirit of Holiness, then the common State of Mortals exercised in the prophane business of this World; I thought it my duty before all things, in the beginning of this little Book, to declare what is necessary to be known to the pious Spagyrist, inflamed with an ardent desire of this Art; as, what he ought to do, and whereunto to direct his aim, that he may lay such Foundations of the whole matter, as may be stable; lest his Building shaken with Winds, happen to fail, and the whole Edifice to be involved in shameful Ruine, which otherwise, being founded on more firm and solid Principles, might have continued for a long series of time. Which Admonition I judged was, is, and always will be a necessary part of my Religious Office; especially, since we must all die, and no one of us, which now are, whether high or low, shall long be seen among the number of Men. For it concerns me to commend these Meditations of Mortality and Posterity, leaving them behind me, not only that honour may be given to the Divine Majesty, but also that Men may obey him sincerely in all things.
