i always believed that when george came up with the concept of the force he has buddhism in mind. just the idea of having no attachment and becoming one with everything. thats the ideal of a buddhist, to have no attachment to worldly possessions, making it easier to let go of one's self and become one..
also, we learn that the 'trick' yoda, quigon, obiwan, and anakin use allows them to maintain their identity...so that would imply that normally you would lose your identity...again, buddhism.
if you are...naughty...then you dont get to become one with everything. you may spend some time in hell to be cleansed of that bad kharma, you may be forced to live a life of suffering, whatever the case you have a different fate, although perhaps you are allowed another chance once you have been purged. so no, i think maul would need to earn the right to sit back and have a beer and a smile with the jedi.
thats what i think anyway
