As physicians have always their instruments and knives ready for cases which suddenly require their skill, so do thou have principles ready for the understanding of things divine and human, and for doing everything, even the smallest, with a recollection of the bond which unites the divine and human to one another. For neither wilt thou do anything well which pertains to man without at the same time having a reference to things divine; nor the contrary.
Above, below, all around are the movements of the elements. But the motion of virtue is in none of these: it is something more divine, and advancing by a way hardly observed it goes happily on its road.
Perceive at last that thou hast in thee something better and more divine than the things which cause the various affects, and as it were pull thee by the strings. What is there now in my mind? Is it fear, or suspicion, or desire, or anything of the kind?
