It is therefore, a source of great virtue for the practiced mind to learn, bit by bit, first to change about in visible and transitory things, so that afterwards it may be able to leave them behind altogether. The person who finds his homeland sweet is a tender beginner; he to whom every soil is as his native one is already strong; but he is perfect to whom the entire world is as a foreign place. The tender soul has fixed his love on one spot in the world; the strong person has extended his love to all places; the perfect man has extinguished his.
