Your worst enemy, he reflected, was your own nervous system. At any moment the tension inside you was liable to translate itself into some visible symptom.
You can love a person dear to you with a human love, but an enemy can only be loved with divine love.[Любить человека дорогого можно человеческою любовью; но только врага можно любить любовью божескою.]
What friends do with us and for us is a real part of our life; for it strengthens and advances our personality. The assault of our enemies is not part of our life; it is only part of our experience; we throw it off and guard ourselves against it as against frost, storm, rain, hail, or any other of the external evils which may be expected to happen.
