Darkness cannot drive out darkness; only light can do that.
Hate cannot drive out hate; only love can do that.

Hate multiplies hate, violence multiplies violence... in a descending spiral of destruction....
The chain reaction of evil--hate begetting hate--must be broken,
or we shall be plunged into the dark abyss of annihilation.

Martin Luther King, Jr., "Strength To Love" (1963)

"The trick is not how much pain you feel—but how much joy you feel. Any idiot can feel pain. Life is full of excuses to feel pain, excuses not to live, excuses, excuses, excuses."

Erica Jong

The pleasantest things in the world are pleasant thoughts: and the great art of life is to have as many of them as possible.

"If you want others to be happy,

        If you want to be happy, 
          practice compassion.”

The Dalai Lama

"If a dog will not come to you after having looked you in the face, you should go home and examine your conscience."
