Is death the end of the road or the beginning of a new life?

There is also a suggestion that it varies from person to person. Some have existed for five thousand years, while some are living for the first time now—fresh as can be.

In principle, that' same how it should be. I can assume that all scholars had more than one life. Their soul "learned" in different bodies, but a certain moment came and then they fully revealed their teachings.
It can also be assumed that if there is a God, then there is his opposite—the Devil. Previously, and now, there is a war of light against darkness. We are the soldiers; He who is above is the general. God is the leader of the light, the Devil of the dark. This war will continue, and probably will never end... If a being of light dies, the soul transfers to another body and continues to fight... Although these are only guesses...
