“You cannot send away a bad thought when it appears in your mind, but you can create other thoughts which will weaken or destroy this bad thought. For example, I may imagine that your friend or neighbor has some drawback, and I may not be able to banish this thought, but when I concentrate on the thought that criticizing another person is bad because I am not perfect, and he has the same God within him as I have within me, then I cannot stop loving this person.”

Leo Tolstoy, A Calendar of Wisdom (Page 322)
