Gandhi

"You must not lose faith in humanity. Humanity is an ocean; if a few drops of the ocean are dirty, the ocean does not become dirty."

"What difference does it make to the dead, the orphans and the homeless, whether the mad destruction is wrought under the name of totalitarianism or the holy name of liberty or democracy?"

"I cannot teach you violence, as I do not myself believe in it. I can only teach you not to bow your heads before any one even at the cost of your life."

"It is better to be violent, if there is violence in our hearts, than to put on the cloak of nonviolence to cover impotence."

"Freedom is not worth having if it does not include the freedom to make mistakes."

"Always aim at complete harmony of thought and word and deed. Always aim at purifying your thoughts and everything will be well."

"You must be the change you want to see in the world."
