You can think about religion simply as a virtual reality game. You invent rules that don’t really exist, but you believe these rules, and for your entire life you try to follow the rules. If you’re Christian, then if you do this, you get points. If you sin, you lose points. If by the time you finish the game when you’re dead, you gained enough points, you get up to the next level. You go to heaven.
When you start to consider how finite your existence and your time and the processes of your brain actually are, you can see how precious the level of mindfulness that requires us to sit up and pay attention really is.
