Signs of events to come must be manifested to whomever prophesies. For prophecy which stems
from exterior illumination is part of that light and seeks to ally with it and bring it into being so
that the part which seems to possess the faculty of understanding is not subject to a sickness of
the mind.
Reason is only too evident. Everything is predicted by divine afflatus (10) and thanks to an
angelic spirit inspiring the one prophesying, consecrating his predictions through divine unction.
It also divests him of all fantasies by means of various nocturnal apparitions, while with daily
certainty he prophesies through the science of astronomy, with the aid of sacred prophecy, his
only consideration being his courage in freedom.
