The numbers don't add up for reincarnation. There are approximately 100 billion dead people and only 6.5 billion people alive. Not everybody can reincarnate into the present and it is doubtful 94 billion achieved true happiness to stop reincarnation. So, no I don't believe in it based on numbers alone.
Hi. I have this idea that our soul is on a journey. There are different levels to this journey like demensions. We go thru many. Maybe the Earth itself is the only HELL and if you don't get it as right as possible you have to go to a have a do over. Maybe we do come back or go to a worse level or better level. Choice is ours. How right do we want to live the first time? reincarnation is like carma.
I think it is a strong possibility. I have read about encounters in which children come in with scars and have recollections in which they are able to tell how these happened and they are verifiable historically or how children speak languages never taught to them in their current life and their stories are tracked down and verified.
If you think of the concept of reincarnation as an aspect of the persent (what you say and do right now) that eventually compounds into the past you can then being to see yourself as reincarnated, just in this portion of your lifetime, moving to a completion of Self. And that is to say,whatever may have happened in the past years and years and still more years ago happened as a result of actions (be they cause or reaction) that occurred some persent time ago.
Further, comtemplate the notion of experiences. How do they play into the concept of reincarnation as well as lessons to learn from an experience, once you realize your in one. In every experience there is something that keeps you anchored there, perhaps more than one thing, which could tie into fears that hold you back from growing beyond the point you keep reincarnating to. Thus, if you check yourself along various lines then you may see that you are holding on to an archaic belief system, behavior or both. You can't evolve. And species evolve as that adapt to changes brought in by those who strive to evolve. I am sure you can think of things brought in by those who have stretch beyond to bring into exsistence products or tools to help you espeacially if your reading this from a computer monitor.
I believe reincarnation as a snag in the evolution of one's growth to becoming Self unconstrained by the boundaries of the concept of time.
