Define heaven and hell

Making a place hell or heaven is in the hands of a individual. Be happy and let others be happy and you can realise what is a heaven.

In simple words, heaven is a place to enjoy and hell is a place of torture,
Heaven is a place where every one would like to go, and hell no one would like to pipe in

Heaven and hell are afterlife fantassy. All pleasures in heaven and all pain in hell. Thereare two sides of same coin- head and tail

I don't think they are fantasy worlds.We believe that all our deeds in this earth will be acknowledged later and will get heaven or hell accordingly.
