Yes there is technology and much more advance than here on earth. Yes there is much more advance computer there, there is future car and plane.

There is reincarnation. It is 100% true. However it is difficult to reincarnate again, most of the time we have to live there around 350-600 years for another reincarnation. Many are longer for 650-2000 years.

1 in 1 million cases, there is a fast reincarnation. Just the time you died, you reincarnate fast. But this is very RARE. Its like a lottery winner. this is special cases. Most of the time when he/she reincarnate, he can still remember about his past life. you can find this more on discovery channel.

some has chosen doesnt want to reincarnate on earth because it is suffering to live on earth, but after hundred of years, this can be change. they want to have reincarnation, because reincarnation is a great asset. you experience from baby to adult in short of time. you can learn many problems here and how to solve them. after you died and go back there you are more clever and wisdom.

However the purpose of getting reincarnate is to pay karma and to be more spiritual evolved person.

There is heaven but only a tiny few of us will reach there. Most of us only reach to plane 2, (earth is plane 1). I believe in 99/100 people will go to either plane 2 or plane 3. heaven is much more above. entering to heaven is impossible if we dont change and live spiritually here.

While Hell is still debatable. I have been to lower astral realm once, and the situation are dirty, little bit dark, there is a statue of devil. but when i think again its just the lower astral realm. If you call this hell, then its hell. There is no fire where people scream. I Dont see anything like that.

many astral travel also claim that there is no hell. Hell is where you are getting punished here on earth, when you have cancer tumor, no hands or leg, that is hell. Hell can be change to heaven as soon as we are living spiritually.
