Compassion- which means, literally, "to suffer with"- is the way to the truth that we are most ourselves, not when we differ from others, but when we are the same. Indeed the main spiritual question is not, "What difference do you make?" but "What do you have in common?" It is not "excelling" but "serving" that makes us most human. It is not proving ourselves to be better than others but confessing to be just like others that is the way to healing and reconciliation.
Few things have done more harm than the belief on the part of individuals or groups (or tribes or states or nations or churches) that he or she or they are in sole possession of the truth: especially about how to live, what to be and do - and that those who differ from them are not merely mistaken, but wicked or mad: and need restraining or suppressing.
