Peace Pilgrim

From January 1, 1953 until her death in 1981, a silver haired woman calling herself only "Peace Pilgrim" walked the streets of this country, spreading her message asking for peace, both inner and outer. She gave up all her possessions and lived completely without money (when people sent her money, she spent it on postage for letters she sent to people who wrote to her -- this was back when snail mail was pretty much it).
She said:

This is the way of peace: overcome evil with good,
and falsehood with truth, and hatred with love.

NEGATIVE vs. POSITIVE: I have chosen the positive approach - instead of stressing the bad things which I am against, I stress the good things which I am for. Those who choose the negative approach dwell on what is wrong, resorting to judgement and criticism, and sometimes even to name-calling. Naturally, the negative approach has a detrimental effect on the person who uses it, while the positive approach has a good effect. When evil is attacked, it mobilizes, although it may have been weak and unorganized before, and therefore the attack gives it validity and strength. When there is no attack but instead good influences are brought to bear upon the situation, not only does the evil tend to fade away, but the evil-doer tends to be transformed. The positive approach inspires - the negative approach makes angry. When you make people angry they act in accordance with their baser instincts, often violently and irrationally. When you inspire people they act in accordance with their higher instincts, sensibly and rationally. Anger is transient, whereas inspiration sometimes has a lifelong effect.
