Some people do know how we can view ourselves and all other people as one family of brothers and sisters. And, clearly, if we all learned this type of respect and love, war, systematic oppression, and most violence would come to an end. That would be a good thing.
But the truth is that no one has every found a reliable way to help people shift their deep perspectives. Even a figure like Buddha or Jesus couldn't do it - if they could, we'd have world peace now.
All I know to do is to live my truth and keep deepening the way that I see myself and others, and share the meditations, prayers, thoughts, and practices I discover and live by with those who will listen.
Would that we would all open our hearts. Often, though, our hearts have to be broken open by the pain of life.
