I find it difficult and more or less a distraction to ask a question like this. I think it is way more useful to act always in a manner that could sustain until the end. Just as ancient philosopher Solon said: " In all things you do, consider the end"
If one behaves that way it is more of a concern to die an honorable death than to speculate on the rewards of an afterlife or rebirth.
In the middleages there were some christian and also islamic mystics who asked the question: "What goes to heaven?" I think this question is also a better question to ask, because no matter what you believe or not believe in, there is always doubt. But let's assume you die and go to heaven, what will go? Your body? I don't think so. Your wordly desires? I don't think so. So it must be the soul ( greek word: psyche), which goes there. In its pure form, without any worldy attachments.
Let's go to the assumption that one will be born again and again. If you act well, then you rise up in status the next life, if you behave wrong, then you will be downgraded.
If I look at all the systems known to me, I really do not think, that this question of what comes after death is important. The question that is important is:
"What do I have to do here?" and this we can only know if we "know ourselves", hence the inscription at the oracle at delphoi: Gnothi Seauton, which means, "know thyself".
This is a very deep answer, thankyou! Not sure I understand it well, but are you saying focusing on the karmic element of 'getting it right' is deflecting from a good moral code?
Also in regards to the question itself, yes it's meant to be quite an 'open question' to create a philosophical flow. The concept of 'what goes to heaven' is quite thought provoking, whatever way we look at it, our bodies do not go with us. If we lose a limb, we cannot connect to that limb mentally when it's gone.
Or can we ?
Not sure if my English is good enough for that. Yes you can call it the karmic element, but it is everywhere. "You reap, what you sow" is from the bible ( i think), other religions have similar proverbs (sayings). I do not know about limb connection, but there is people who still feel their arm, after they lost it and it is painful and numb. in neurology they found some evidence as well, that if somebody loses a hand for example, the neurons in the brain, that were responsible for moving this hand change their function and "help" out the other hand. That way some people can learn to use their left hand ( after they lost their right ) in a way they never could have imagined.
