Reincarnation is a funny thing. When you "die" you lose all memories of your former life and return as someone else not necessarily a human. What is so funny is that above statement is exactly the same as to say when you "die" babies will be born immediately after your death. The problem lies in people not knowing who they really are.
Who really are we?
The law is karma, not chance.
Who established the law?
It is not that sort of law. It is more like the law of gravity; it describes what happens: "As you sow, so shall you reap."
There is no rule and no law. Also it is not chance. There is no determinism or fatalism. You asked a question of who really are we? Who is asking this question?
That sounds like a non-answer. If something reincarnates as anything...there has to be a reason as to why. Something has to determine the why.
Why is there a God? There must be a why. Are you not I? Do you say "I am going to the store." I am I also we are all I's. Reincarnation is simply a reincarnation of I's. No hocus pocus involved. There will be births after your death that is reincarnation.
What is the illusion hiding? Something created the illusion? Was the illusion created by the illusion?
There is one event. The event is happening.
You seem to be hung up on there must be a creator who created God? There must be.
Yes, you created it. Just like you create the illusion of water in a mirage. What you thought was water, wasn't. It was just the deceptive illusion of water.
Yes the ego is a funny thing.
God always was.
Well then, we have found the answer you seek.
Yes we are all I's and all the one event. There is an event going on. What is involved is the one event. People tend to chop things into bits and pieces then forgot they did so.
So, that would be the Buddhist believe God choses who you will reincarnate into.
