Every dark clouds have a silver lining
Yes, it is a very true statement. Even if the sky is covered with dark clouds and the sun is hidden behind there may occur a flashing that would lighten the surroundings in a moment. This statement highlights that where
there is darkness there is light. That teaches us to be optimistic and not to loose hope because the sooner or later solution will come to you in the form of lighting that is seen clearly in the darkness. When there is a misery and sorrow all around there is happiness too, we need to find it. Life is cycle of sorrows, misery, happiness and cheer. When you are going through a problem have faith that happiness is on the way. The proverb reminds us to stay on the way of life and not to get lost because the sky may be covered with dark clouds, there may be heavy raining but it is temporary. Soon the sun will appear. We should no forget that if there is no darkness there is no meaning of light similarly if there is no sorrow there is no enjoyment of happiness.
So from now we shall always be optimistic because if you lost hope you have lost every thing.
