from Buddhist practice, encountered while reading Karen Armstrong's Twelve Steps to a Compassionate Life
It will help you to appreciate how dependent you are on people you have never met and who may live far away. As you walk around your home, bring to mind all the people who built it, treated its timbers, baked its bricks, installed the plumbing, and wove your linens. When you get up in the morning, remember those planted, picked, and spun the cotton of your sheets and who collected, treated, and exported the beans you grind for your morning coffee. You enjoy their products, so you have a responsibility for them, especially if they were working in poor conditions. Who baked the bread you toast for breakfast? Become aware of the labor that went into the production of each slice. As you set off to work, reflect on the thousands of workers and engineers who build and maintain the roads, cars, railroads, planes, trains, and underground transport on which you rely. Continue this exercise throughout the day. We should also make ourselves aware that our cultural, ethical, religious, and intellectual traditions have all been profoundly affected by other peoples'. We think of them as ours, but they may in the past have been deeply influenced by the ancestors of those we now regard as enemies. We are what we are because of the hard work, insights, and achievements of countless others.
Peace.
