Gnostic Salvation is the Escape from matter and the reunification with the true God, I believe this is literal for there is no point in claiming we are obtaining salvation and "Gnosis" if we are just constantly reincarnated and recycled into the parameters of material suffering again, never able to achieve our goals, why?
