Torah, Deuteronomy, 10:06 – 10:07: The children of Israel journeyed from the wells of B’nei Ya’akan to Moserah; there Aaron died, and there he was buried; and Eleazar his son served as Kohen in his stead. From there, they journeyed to Gudgodah, and from Gudgodah to Yotvath, a land with streams of water.
Death in the spiritual world isn’t a punishment or something terrible. When the son comes to replace the father it means the rise, for example of Aaron, to the next level.
It means he dies in his last guise, in his past performance of some actions, because he can’t rise to the next level without leaving his previous form. Then he obtains a new form that is called his son. But in principle, all souls are immortal.
They don’t lose anything; they only gain all the time. In other words, it is about a desire that transforms under different names until it comes to its final corrected state.
