Remember that the promise of desire is the attainment of what you desire, that of aversion is not to fall into what is avoided, and that he who fails in his desire is unfortunate, while he who falls into what he would avoid experiences misfortune.If, then, you avoid only what is unnatural among those things which are under your control, you will fall into of the things which you avoid; but if you try to avoid disease, or death, or poverty, you will experience misfortune.Withdraw, therefore,your aversion from all the matters that are not under our control and transfer it to what is unnatural among those which are under our control. But for the time being remove utterly your desire;for if you desire some one of the things that are not under our control you are bound to be unfortunate; and, at the same time, not one of the things that are under our control, which it would be excellent for you to desire, is within your grasp. But employ only choice and refusal, and these too but lightly, and with reservations, and without straining.
