I hadn't realized the mundane teachings you were referring to were couched in terms of being reborn into a better life

Well mundane teachings generally reflect around rebirth and kamma to encourage people into morality don't you think. I think even the Buddha did that according to the suttas. There are people who are not interested in going forth thus they have been taught according to their beliefs and the lengths they are willing to go.

My point is that, teachers generally should reflect both teachings in their talks so that practitioners are aware what is what and choose to select what works for them rather than be deluded into something.
