Spirituality means waking up. Most people, even though they don't know it, are asleep. They're born asleep, they live asleep, they marry in their sleep, they breed children in their sleep, they die in their sleep without ever waking up. They never understand the loveliness and the beauty of this thing that we call human existence. You know, all mystics - Catholic, Christian, non-Christian, no matter what their theology, no matter what their religion -- are unanimous on one thing: that all is well, all is well. Though everything is a mess, all is well. Strange paradox, to be sure. But, tragically, most people never get to see that all is well because they are asleep. They are having a nightmare.
