You can resist evil without resorting to violence.Non-violence seeks to create friendship and understanding, not humiliate those who oppose you.It is evil itself that must be opposed, rather than seeing the people committing evil acts as the enemy.Being committed to non-violence means being willing to suffer, if necessary, for the sake of what is right.Non-violence applies to the attitude of our hearts as well as to outward actions.Those pursuing change through non-violent means maintain hope for the future and work patiently toward that day of better justice.
