All the things taking place around our world, all the irritations and all the problems, are crucial. Without others we cannot attain enlightenment — in fact, we cannot even tread on the path. If there is no noise outside during our sitting meditation, we cannot develop mindfulness. If we do not have aches and pains in the body, we cannot attain mindfulness; we cannot actually meditate. If everything were lovey-dovey and jellyfishlike, there would be nothing to work with.
