The masters also extol humility above many other virtues. But I extol detachment above humility for this reason: humility can exist without detachment, but perfect detachment cannot exist without perfect humility, for perfect humility ends in the destruction of self. Now detachment comes so close to nothing, that between perfect detachment and nothing no thing can exist. Therefore perfect detachment cannot be without humility. But two virtues are always better than one.
