There is Life but it is not about GOD or Heavens. Near death exp says nothing about reality. Life after death .... Westerners are so blind on this topic. Yes there is life after death but near death experience tell you nothing about it. There is a lot to say I cannot explain in this little space. I will state one point here that someone brought up about candlelight. Yes energy is conservative. It never destroy. So is your energy (cosmic consciousness or cosmic energy) . When one ask what happen to the energy? The other person said ..Oh its like candlelight it goes away. But the fact he misses out in that is if u are million light year away. If you have a good telescope you can see the candlelight that went off million light years ago. Just like stars in the sky. So is your energy.. It travels so fast until it find another sources to settle. Another life form to restore. The strength it travel depends on your power of happiness/lightness/purity ("karma"). If you are week u may not absorbed to high resources where you will born as animals. If you are strengthened by good karma you will absorbed to stronger resources like another human life of higher dimension like heavens. If u are weak ...You will stuck in lower dimensions oh trapped in as ghosts for some times.
How do you know this is true?... There is a easy way to find by build up on meditation. Since you born you keep feeding images from 5 sensors. By what you see, By what you taste, By what you smell, By what you hear, and By what you touch. So the world you build by these facts makes you a world (an illusion). All your thoughts build upon this and you cannot think out of it. But if you can stop engaging thoughts that you gain from all these 5 sensors for a 1 minute.... That minute you are in your original state. If you improve you can start reading your original state. Then you can find how much power you have. You can also find where you came from if you improve this ability. Trust me this is not magic. It is so logical and anyone can achieve it if you try enough. There is no magic in this world it is all unproven science matters.
There are tones of cases about REINCARNATION listed out there. Especially when kids before they build up their world over above sensors they appear to have access to his/her original form. Where someone can investigate about where they from. Read articles by Kevin Williams or ian Stevenson.
