With lots of twists and turns, the movie ends up in two very different places - all because of a sliding door. Each of us, probably every day, has countless turning points in our lives kind of like the sliding door incident most of which we aren't even aware of, we don't even know they happen - we simply move ahead. We all do this, this looking back and wondering. In fact, some obsess about it while others aren't so ritualistic or compelled, and still others just give occasional attention to these past turning points. But we all do it because these turning points are often looked at as meaningful - in large or small ways they have changed the course of a life, usually our lives.
Every religion has a particular way of meaning-making that is unique, it's their own path.
If you personalize this path it's called faith. Because after such a sharing and maybe some discussion, it would become clear that every faith tradition has it's own corner on the meaning-making process. And this is my point. We're all looking for meaning, and there's all these many, many ways to go and get it, shape it, understand it. Of course, if it was just this easy, if this is where it ended, it would be okay.
