XXXIV. (187) Abandoning therefore your superfluous anxiety to investigate the things of heaven, dwell, as I said just now within yourselves, forsaking the land of the Chaldeans, that is, opinion, and migrating to Charran the region of the outward sense, which is the corporeal abode of the mind. (188) For the name Charran, being interpreted, means “a hole;” and holes are the emblems of the places of the outward sense. For in some sense they are all holes and caves, the eyes being the caves in which the sight dwells, the ears those of hearing, the nostrils of those smelling, the throat the cavern of taste, and the whole frame of the body, being the abode of touch. (189) Do ye therefore, dwelling among these things, remain tranquil and quiet, and investigate with all the exactness in your power the nature of each, and when you have learnt what there is good and bad in each part, avoid the one and choose the other. And when you have thoroughly and perfectly considered the whole of your own habitation, and have understood what relative importance each of its parts possesses, then rouse yourselves up and seek to accomplish a migration from hence, which shall announce to you, not death, but immortality; (190) the evident proofs of which you will see even while involved in the corporeal cares perceptible by the outward senses, sometimes while in deep slumber (for then the mind, roaming abroad, and straying beyond the confines of the outward senses, and of all the other affections of the body, begins to associate with itself, looking on truth as at a mirror, and discarding all the imaginations which it has contracted from the outward senses, becomes inspired by the truest divination respecting the future, through the instrumentality of dreams), and at other times in your waking moments. (191) For when, being under the influence of some philosophical speculations, you are allured onwards, then the mind follows this, and forgets all the other things which concern its corporeal abode; and if the external senses prevent it from arriving at an accurate sight of the objects of the intellect, then those who are fond of contemplation take care to diminish the impetuosity of its attack, for they close their eyes and stop up their ears, and check the rapid motion of the other organ, and choose to abide in tranquillity and darkness, that the eye of the soul, to which God has granted the power of understanding the objects of the intellect, may never be overshadowed by any of those objects appreciable only by the outward senses.
