And the first branch of science to which I felt inclination was medicine. It had a great attraction for me because I recognised its excellence and the more I acquired it the more I loved it and the more earnestly I studied it. Now when I had progressed sufficiently far to think of treating invalids I took counsel with myself and reflected in the following manner on the four objects for which mankind so earnestly strive. "Which of them shall I seek to acquire with the help of my art, money, prosperity, fame, or reward in the next world"? In the choice of my calling the decisive factor was my experience that men of understanding praise medicine and that the adherents of no religion censure it. I found, however, in medical literature that the best physician is he who by his devotion to his vocation strives only after a reward in the next world; and I resolved to act accordingly and not to think of worldly gain, so that I may not be likened to the merchant who sold for a worthless bead a ruby by which he could have acquired a world of wealth. On the other hand, I found in the books of the ancients that when a physician strives after the reward in the next world by means of his art he thereby forfeits no fraction of his worldly guerdon but that therein he is to be compared with the peasant who carefully sows his plot of ground to acquire corn and who subsequently without further effort gets along with the harvest all manner of vegetation. [The cultivator along with the harvest gets grass and vegetation which may serve as a pasture for cattle.] [Sidenote: Burzoe starts practice.] I, therefore, directed my attention to the hope of securing recompense in the next world by curing the sick and was at considerable pains in the treatment of all the deceased whom I hoped to cure and even such as were past all such hopes, whose suffering I endeavoured at least to alleviate. I personally attended those I could; but where this was not possible I gave the patients the necessary instructions and also sent medicine. And from none of those whom I so treated did I demand payment or other return. I was jealous of none of my colleagues who was my equal in knowledge and who excelled me in repute and riches; although as a matter of fact he was lacking in equity and good manners. When, however, my soul felt inclined to impel me to be jealous of such and to be covetous of a situation like his I met it with severity in the following manner:-- [Sidenote: Burzoe addresses his own soul.
