2.  We must strive after a quiet mind.  As well might the eye ascertain an object put before it while it is wandering restless up and down and sideways, without fixing a steady gaze upon it, as a mind, distracted by a thousand worldly cares, be able clearly to apprehend the truth.  He who is not yet yoked in the bonds of matrimony is harassed by frenzied cravings, and rebellious impulses, and hopeless attachments; he who has found his mate is encompassed with his own tumult of cares; if he is childless, there is desire for children; has he children? anxiety about their education, attention to his wife, γυναικὸς φυλακή, rather “guardianship of his wife.” care of his house, oversight of his servants, οἰκετῶν προστασιαι, rather “protection of his servants.” misfortunes in trade, quarrels with his neighbours, lawsuits, the risks of the merchant, the toil of the farmer.  Each day, as it comes, darkens the soul in its own way; and night after night takes up the day’s anxieties, and cheats the mind with illusions in accordance.  Now one way of escaping all this is separation from the whole world; that is, not bodily separation, but the severance of the soul’s sympathy with the body, and to live so without city, home, goods, society, possessions, means of life, business, engagements, human learning, that the heart may readily receive every impress of divine doctrine.  Preparation of heart is the unlearning the prejudices of evil converse.  It is the smoothing the waxen tablet before attempting to write on it. Rather “for just as it is impossible to write on the wax without previously erasing the marks on it, so is it impossible to communicate divine doctrines to the soul without removing from it its preconceived and habitual notions.”
