Reincarnation: beginning and ending

It is a wrong conception when theosophists believe that reincarnation had no beginning and will have no ending. […] It is only a certain period of time in earth evolution during which mankind reincarnates. It was preceded by a most spiritual condition which precluded any necessity for reincarnation and there will follow again a spiritual state which will likewise obviate the necessity for reincarnation.
