In the march towards Truth, anger, selfishness, hatred, etc., naturally give way, for otherwise Truth would be impossible to attain. A man who is swayed by passions may have good enough intentions, may be truthful in word, but he will never find the Truth.
If we ourselves remain angry and then sing world peace, it has little meaning. First, our individual self must learn peace.
