It is extraordinary to think how one man can have had such significance in so many lives. This quote provides valuable insight and perspective:
“I mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even an enemy. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate, only love can do that.” Martin Luther King Jr.
According to one source, the quote is a hoax (though no proof is offered). It is a beautiful quote, whoever penned/said it.
Whether or not MLK really said this, it is, indeed, beautiful and appropriate to this moment. The last sentence comes from the Dhammapada, verses attributed to (but not really written by) the Buddha.
