What happens after death? Is conversion possible after death? Why did Jesus descend into Sheol? Will the souls of the dead roam around and possess people? Will children be punished by God for the sins of their parents and ancestors? Can one atone for the sins of previous generations? If yes, how? Angels and demons – are they real or just the creation of human imagination? What are the evil spirits that possess people? Are they real spiritual beings or the unconscious mind taking control of the person? Who is Satan? What does Satan do? This book tries to give an answer to these and several other similar questions in the light of the Bible and the official teachings of the Catholic Church. It will be an excellent guide in matters of Catholic faith concerning life after death and the world of spirits.
