Doing good deeds... that's the highest religion.
I agree in part. I think that the highest religion would not be limited to good deeds, but would also include positive and virtuous thinking. Clearly, though, good deeds on the surface seems more important, but without a foundation of virtuous thinking and habits I wouldn't think that a person would be able to do too many good deeds, and would certainly be able to do a lot more good deeds with an excellent foundation of virtuous thought and habits.
Also, if it ever happens that ones reality is perfect, and no one is lacking anything, good deeds I think would be replaced by something else. Maybe a greater emphasis on enjoying life in a perfect world. But under the current circumstances I agree that good deeds come first.
Another thing, I wouldn't call that a religion. I think that it would be better thought of as a philosophy. Religion caries with it too much baggage that isn't concerned strictly with a desire to do good and to think virtuously.
If there's a god (or some sort of justice like karma or whatever), who do you think will be rewarded?
If God would be the kind of God I would expect, then I think that everyone would be in a sense rewarded in one way or another. For instance, if a criminal had a terrible and evil life here, I would expect that God would make things easier for him in the future. I would expect that God would not turn his back on anyone, even the worst criminals and mass-murderers, but would help everyone to grow and develop. Having said that, I think there are few scenarios where evil and suffering can be explained in a way that doesn't make God look like an evil being. I think that would be one of the first things Id ask God, if not
the first thing - why does he allow suffering and evil? Hes got a lot of explaining to do.
