"Be grateful to everyone" is about making peace with the aspects of ourselves that we have rejected... If we were to make a list of people we don't like - people we find obnoxious, threatening, or worthy of contempt - we would discover much about those aspects of ourselves that we can't face... other people trigger the karma that we haven't worked out.
Pema ChodronOne of the main discoveries of meditation is seeing how we continually run away from the present moment, how we avoid being here just as we are. Thatโs not considered to be a problem. The point is to see it.
