I've been observing others and notice that a lot of people do not have peace in them because they are not generous enough to tolerate others who might have offended them either unintentionally or deliberately, or who have not lived up to their expectations. Examples are getting bothered by someone who has an odd mannerism; being disappointed in someone not showing any consideration or gratitude for what he has received; seeing someone not acting in accordance with conventional custom... These are really forms of judging on the same level as gossiping. If you cannot tolerate such others, how can you expect God to tolerate you? Just let them all go in God so that you may have peace in you.
