Mahatma Ghandi said:
"Non-violence and truth are inseparable and presuppose one another."
"Non-violence is not a garment to be put on and off at will. Its seat is in the heart, and it must be an inseparable part of our being."
"Nonviolence is the first article of my faith. It is also the last article of my creed."
"Non-violence is the greatest force at the disposal of mankind. It is mightier than the mightiest weapon of destruction devised by the ingenuity of man."
"Non-violence, which is the quality of the heart, cannot come by an appeal to the brain."
And
"Non-violence requires a double faith, faith in God and also faith in man."
