"Gradually, each human spirit-soul is purified so that it may become a highly advanced spirit, just as flowers bloom, bring forth fruit, and eventually mature. The soul who committed misdeeds undergoes a process of atonement. Having successfully worked through this, it is able to move on to further spiritual growth. Some very advanced psychics are conscious of this process taking place."
