Our reading
An editorial interpretation.
Darkness stands for difficult times, while turning on a light suggests an action that makes happiness visible again. The sentence presents hope as something that can be rediscovered. Its gentle image gives an encouraging form to the claim that bleak circumstances need not exclude happiness.
