Here's some of it, talking about how man is like an instrument, which is his signature.
Further we are to know, that though one fiat thus keeps the upper hand, and figures the form according to itself, that yet the other two give their sound, if their instrument be but played upon; as it is seen that many a man, and also many a beast, though it is very much inclined either to good or evil, yet it is moved either to evil or good by a contrary tune, and often lets its inbred signature [or figure] fall, when the contrary tune is played upon his hidden lute or form: As we see that an evil man is often moved by a good man to repent of and cease from his iniquity, when the good man touches and strikes his hidden instrument with his meek and loving spirit.
And thus also it happens to the good man, that when the wicked man strikes his hidden instrument with the spirit of his wrath, that then the form of anger is stirred up also in the good man, and the one is set against the other, that so one might be the cure and healer of the other. For as the vital signature, that is, as the form of life is figured in the time of the fiat at the conception, even so is its natural spirit; for it takes its rise out of the essence of all the three principles, and such a will it acts and manifests out of its property
