Paramahansa Yogananda: "The soul has worn many garbs: today you are an American and in the next life possibly Chinese, and so on. That is why it is unwise to hate any nationality, for hate attracts just as love attracts. Anything you hate, you attract to yourself that you may may learn to overcome that prejudice. That is the law. For instance, those who hate dark race will be born in that race --- invariably. The greater the hatred, the stronger will be the karmic attraction to the object hated.
