10. Wherefore, since it is our duty fully to enjoy the truth which
lives unchangeably, and since the triune God takes counsel in this
truth for the things which He has made, the soul must be purified that
it may have power to perceive that light, and to rest in it when it is
perceived. And let us look upon this purification as a kind of journey
or voyage to our native land. For it is not by change of place that we
can come nearer to Him who is in every place, but by the cultivation
of pure desires and virtuous habits.
