The opposition of reincarnation will argue that the population of the world increases every year. Where were the seven billion souls that exist today? The believers of reincarnation will counter that evolution is the process by which souls are created from lower species. This is why the population of the world increases daily.
If one believes in evolution and reincarnation, is it possible for humans to regress to a lower species in the animal world. May we rephrase this as “regrution”, the regression of a soul to a lower species? What would cause a soul to return in a lower animal form? In the Book of Prophecy (Ofudesaki) is the following
Think about the present concept of future paths to cows.
Let all of you in high places beware. 4-18
Until now there has been much talk of rebirth as oxen or horses,
but there has been no one who knows his past or future. 5-1
If you let your debts (sins) pile up,
a path of oxen and horses will finally appear. 8-54
What does God do with these people who cause sufferings to others? Many believe that they will go to hell or damnation. Regrution may be the process by which God deals with the most evil?
