What's the long term pattern of Life/Death pack

Hello,

I'm learning the things in the pack, but just want the big overview of how it works.

Is it: 

• When you die you become a ghost so that you can do whatever you need to do to "rez" again?
• Is what you need to do to "rez again" something that can be finished before you die?
• Do you need to advance skills as a ghost as a prereq to rez again?
• When you rez again, what do you hold onto from the previous life? Relationships? Traits? (Like ones you get from completing tasks / goals)?

Just looking for a description of the entire life-cycle from birth, to death, to ghost, to re-birth.

Thanks for any feedback.
