A quote
If you once convince yourself of this, and if you come to love virtue devotedly (for mere loving is not enough), anything that has been touched by virtue will be fraught with blessing and prosperity for you, no matter how it shall be regarded by others. Torture, if only, as you lie suffering, you are more calm in mind than your very torturer; illness, if only you curse not Fortune and yield not to the disease—in short, all those things which others regard as ills will become manageable and will end in good, if you succeed in rising above them.
