I have gather some things about this topic.
Let us begin here:
Can there be made a case for reincarnation:
What do others have to say:
As I see it someone has to be born in Africa...why not me? I have no problem with that. But who knows? Maybe I will be born in India next time. That would just be great. Then Sadhguru could be my father or should he be your father? Are we to fight about the bodies? I want this body...this family...not this body...this family...hmm...who desides these things?
When everybody has become like Sadhguru then there will be no problem incarnating on the planet. The question will then be...what now? Are we to leave the planet? I think there will be people who want to experience being parents and living in a peaceful world.
