Where there is light in the soul there will be beauty in the person.
Where there is beauty in the person there will be harmony in the home.
Where there is harmony in the home there will be honor in the nation.
Where there is honor in the nation there will be peace in the world.
— Ancient Chinese

Comment: Even if things are difficult on the material level, with a focus on the positive, your personal spiritual connection can be lighthearted. It may not change your mood, but you can be heartened in your faith.
