Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Martin Luther King, Jr.
Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before. Edgar Allan Poe
Hope is being able to see that there is light despite all of the darkness. Desmond Tutu
I will love the light for it shows me the way, yet I will endure the darkness because it shows me the stars. Og Mandino
Even a happy life cannot be without a measure of darkness, and the word happy would lose its meaning if it were not balanced by sadness. It is far better take things as they come along with patience and equanimity. Carl Jung
