What is the reason why people are born and die from the beginning of the world? What is the cause that we see good mixed with evil in everything around us? What is the way for humans to escape the hammer and anvil of relentless Duality? "Sefer HaGilgulim" answers these questions and presents in detail the doctrine of Reincarnation, as developed by the Kabbalist Isaac Luria in the sixteenth century and recorded by his disciples. It is a comprehensive understanding of Reincarnation, completely different from the simplistic and simplified view that is prevalent today.
