As for shortening a distance for which the name travel is given, it is necessary in the tongue and does not take into account distance or proximity. It is the one whose knowledge takes into account those responsible. Whoever travels among them will shorten. If a person travels with his sight for consideration, then he will shorten. If he also travels with his hearing, he will shorten, and if he travels with his thought in the intelligibles, he will shorten, and the form of his shortening is shortening of his sight. According to what he gives him in his time, if he gives him all of it, it is according to him, and if he gives him some, it is according to him, and this is the doctrine of the group, and they rely on it.
