A lot of people have argued that the S06 LA timeline (LAX-timeline) is the epilogue of Lost; a mirror of the previous timeline. Others have suggested it's what would have happened, if the Island never existed. I would like to expand their arguments, and say the LAX-timeline is the KARMIC epilogue of the Losties. Or that is to say, we're seeing a preview of the Losties in their next spiritual awakening.
We know reincarnation is a concept in the Lost cosmology, given the scene of Richard Alpert testing Locke, in 'Cabin Fever'.
World religion underlies alot of the subtext of Lost, especially Hinduism. A tenet of Hinduism is Samsara, and the concomitant of Karma. Samsara in its simplest definition is the cycle of birth, death, and rebirth. Karma is a concept in Hinduism which explains causality through a system where beneficial effects are derived from past beneficial actions and harmful effects from past harmful actions, creating a system of actions and reactions throughout a person's reincarnated lives [1].
Also, it seems most of the Lostie die after redeeming themselves. Redemption is a path of enlightenment.
In the LAX timeline, we are witnessing Karma @ work.
Hurley
=======
Hurley is cursed in the Island timeline. After karma, Hurley is the luckiest person in the world.
Jack
=======
Jack is a broken man with daddy issues. After karma, Jack seems to be able to resolve his daddy issues, by being the father he never had.
Sawyer
=======
Sawyer is an outlaw, and a man living @ the edges. After karma, I hope we'll see him happily rooted in love with Juliet; possibly a good man.
Ben
=======
Ben yearns for power, and total authority; He's a bit of a dick. After karma, I hope we'll see him getting fired, and having to work underneath Randy @ a Cluck's Chicken Shack. That would be karmic justice!!!
I'm still figuring out what would be the karmic balance for the other losties.
p.s. If this the LAX timeline is the next spiritual awakening for the Losties, all the losties will die on the Island.
