There are several supreme states of being. Each is a type of enlightenment. It is possible to reach such supreme states by taking the path of darkness, or of light, or remaining neutral or somewhere in between. At the moment of enlightenment, one can choose a different path, or one can graduate and move to a different universe and start over there. Everyone will eventually get to the same place.
Reincarnation is fun and exciting and is a fast way to learn.
Karma demands that one reincarnate and replay karmic debts. Contracts are binding. There is, there must be, a better truth, a higher truth, a purer and cleaner truth. The fruit of lies is broken trust, cynicism, an inability to trust, an unwillingness to hope. For if we completely give up hope, then we too are lost, and we too feed the black pit of despair and helplessness that we so despise in others.
