Enlightenment, or Nirvana (which means "going out") is to be found in the elimination of Karma and the accompanying craving/aversion that bedevils us all. The extinction or "going out" of Enlightenment is the extinction of the very damaging notion that we are all separate discreet entities. Instead, Enlightenment focuses on finding unity with reality as it is, and not as we wish it to be, as this world is indeed a temporary illusion.
