Reincarnation:   To an embodied soul desire and aversion will naturally occur.  On account of these states, karmic matter clings to the living being.  The karmic bondage leads the living being through the four states of existence.  Entering into the state of existence, the living being builds its own appropriate body.  Once embodied, he gets the senses.  Through the senses,  objects in the environment are perceived.  From perception comes desire or aversion for those objects, and from this the cycle begins again.  But the cycle ends in the case of those who will attain liberation, whereas it is unending to those who will not.

Reincarnation in the Bible

        Because reincarnation was such a universally accepted idea, no direct reference was made to it in the New Testament.  But there are several indirect references:  

 

       And the disciples asked him, saying, "Why then do the scribes say that Elijah must come first?"

       But he answered them and said, "Elijah indeed is to come and will restore all things. But I say to you that Elijah has come already, and they did not know him, but did to him whatever they wished. So also shall the Son of Man suffer at their hand."

      Then the disciples understood that he had spoken of John the Baptist." 

                                                                              (Matthew 17:10-13, see also Mark 9:9-13)

      

      Here Jesus clearly says that John the Baptist is a reincarnation of the prophet Elijah. And again:

 

      As Jesus was walking along, he saw a man who had been blind from birth.

     "Teacher," his disciples asked him, "why was this man born blind? Was it a result of his own sins or those of his parents?"
    
 "It was not because of his sins or his parents' sins," Jesus answered. "But it is the works of God that are manifested in him"                                                                   (John 9:1-3)

 

        Here it is very clear that the disciples believed in reincarnation - that the blind man may have sinned before he was born in this life.  Jesus does not renounce reincarnation here, but merely says that the blindness is the working of God. (Natural law.)  Then in the Old Testament we have a very clear reference: 

 

        The word of the LORD came to me thus:  Before I formed you in the womb I knew you.  Before you were born I dedicated you, and appointed you to be a prophet to the nations."   (Jeremiah 1:4-5)

 

        Finally, in the fifth century, the emperor proclaimed that reincarnation was not a Christian doctrine.  Why would he have done this if no Christians were believing in it, or if only a small minority of Christians were believing in it?
