"Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that." – Martin Luther King, Jr.

Simple: Darkness cannot make darkness go away. Only light can make darkness go away. Hate cannot make hate go away. Only love can do that.
What it means: Hatred cannot be resolved with more hatred. Only love can keep people from hating each other.
