Advent! In the Sunday Gospel passage Jesus is saying, “Stay awake, praying at all times”.
Praying at all times? Is it possible? Is it even safe? If you are driving a car or performing a surgical operation reading a prayer-book, for example, isn’t advisable. Well, try looking at it this way: If a mother is holding a restless very young baby on her hip while adjusting the flames on the stove she can’t be concentrating on the baby – at least, not explicitly. But at some level deep down in her mind she is aware of the baby (otherwise she’d drop it!). The quality of that awareness depends on how she relates to the baby at he times when she is free to.
Or a different example: you are a passenger in a car driven by your friend. You both have all sorts of things to talk about that occupy your mind. And yet you do get to your destination. The driver has been concentrating on what you have been saying… and concentrating too on the road, but at a different level of awareness. The quality of that concentration depends on how well you relate to each other when you’re really free to, and how well the driver concentrated on driving when learning to.
