I am concerned about a better world.
I'm concerned about justice.
I'm concerned about brotherhood.
I'm concerned about truth.
And when one is concerned about these,
he can never advocate violence.
For through violence you may murder a murderer
but you can't murder murder.
Through violence you may murder a liar
but you can't establish truth.
Through violence you may murder a hater,
but you can't murder hate.
Darkness cannot put out darkness.
Only light can do that. . . .
