There are a number of qualities which are important for mental peace, but from the little experience I have, I believe that one of the most important factors is human compassion and affection: a sense of caring.
The roles we play in each other's lives are only as powerful as the trust and connection between us--the protection, safety, and caring we are willing to share.
Don't be careless about yourselves--on the other hand not too careful. Live well but do not flaunt it. Laugh a little and teach your men to laugh--get good humor under fire--war is a game that's played with a smile. If you can't smile, grin. If you can't grin, keep out of the way till you can.
What distinguishes our species is thought. The cerebral cortex is in a way a liberation. We need no longer be trapped in the genetically inherited behavior patterns of lizards and baboons: territoriality and aggression and dominance hierarchies. We are each of us largely responsible for what gets put in to our brains. For what as adults we wind up caring for and knowing about. No longer at the mercy of the reptile brain we can change ourselves. Think of the possibilities.
If you shift your focus from yourself to others, extend your concern to others, and cultivate the thought of caring for the well being of others, then this will have the immediate effect of opening up your life and helping you to reach out.
We are a caring nation, and our values should also guide us on how we harness the gifts of science. New medical breakthroughs bring the hope of cures for terrible diseases and treatments that can improve the lives of millions. Our challenge is to make sure that science serves the cause of humanity instead of the other way around.
There is a word in South Africa - Ubuntu - that describes his greatest gift: his recognition that we are all bound together in ways that can be invisible to the eye; that there is a oneness to humanity; that we achieve ourselves by sharing ourselves with others, and caring for those around us.
I'm less interested in how we label ourselves. I'm more interested in how we treat each other. And if we're treating each other right, then I can be African-American, I can be multi-racial, I can be you name it, what matters is, am I showing people respect, am I caring for one, for other people.
Change begets change. Nothing propagates so fast. If a man habituated to a narrow circle of cares and pleasures, out of which he seldom travels, step beyond it, though for never so brief a space, his departure from the monotonous scene on which he has been an actor of importance would seem to be the signal for instant confusion. The mine which Time has slowly dug beneath familiar objects is sprung in an instant; and what was rock before, becomes but sand and dust.
Meditation is valuable for all of humanity because it involves looking inward. People don't have to be religious to look inside themselves more carefully. It is constructive and worthwhile to analyze our emotions, including compassion and our sense of caring, so that we can become more calm and happy.
