Based upon your karmic life, as you sow, so shall you reap etc, most people will go to the astral realm and the numerous heavens and hells that are there.
Most old school Spiritual civilisations and groups even today believe in infinite heavens and infinite hells in the astral realms, well the lower astral realms to be precise.
Within this place (which could hold the place where suicide bombers get 40 virgins or so and goats and lambs and such - depending on which Muslim you talk to) you will leave out a period of time, before you work off whatever energy/karma you need to work off depending upon your life deeds and then maybe return back to earth, or a physical realm to work off more energy.
Yet above this, you also have the higher astral realms where people who lived far more pious, stoic, spiritual lives will retreat to. - beyond that, there is a region of higher mind, beyond that, the spiritual realms that include no mind.
The overall concept from all civilisations that practised these more pagan beliefs of life after death that included a lot of Shamanic/druidic practices is a life without mind and control of the mind can escape you from being reborn again because you have gone beyond the passage of the mind.
For instance, a lot of what Jesus said was due to the influence of past civilisations that the Jewish establishments/systems didn't like, supposedly was taught a lot from far eastern and middle eastern practices - which made up what was written in the new testament and why there is such a difference between the new and old testament. There also was still as strong pagan type belief system evident throughout the mediterranean at this point.
Of course we don't believe this anymore because we think we have all the answers. It may take wars, evasive surgery, painful therapy in hospitals and countless amounts of conversations about drugs, sex and relationships on TV and in our lives - but yeah, we have the answers, it's just having the answers is so time consuming because we're so clever now.
