It seems like Peter is usually making the same point: keep your eye on the ball.
Is it useful? What is the logical outcome of x, y or z? All the while keeping practice and progress in mind.
I like it
I admit that I haven't read through this whole thread, just a few of Peter's posts. But this suggestion, to consider what is useful and practical seems much more useful than the endless poking at rebirth. I wrote this in another forum and I believe it's true:
If you don't believe in rebirth, hurry up and focus on the here and now! It's all you have, so make the most of it. If you do believe in rebirth, meditate like your hair was on fire! This is a rare opportunity. The same urgency applies in both cases.
