Are we to serve endlessly?

I forgot which thread I read it from but there was a passage that says that we stay incarnating in 3rd density until 4th density graduation. I had no idea this was the case until today. If that's the case then it makes sense that we've been incarnating here for a very long time (I know I have) and that the passage in LOO about being swept up in karma makes us being here as wanderers much more dangerous a mission. If you don't graduate then you essentially lost your 4th, 5th, 6th density progress from other lifetimes.
