Life is hell.  Death is heaven.  Most of my life has been struggle, only last year did I have a glimpse of death (ego death/nirvana), heaven and the infinite love that surrounds you when you're free from ego.  Let me tell you, take the happiest moment of your life and multiply it by 1000x and then you might be able to contrast that to heaven.  It is a whole nother level of peace that I cannot effectively portray through words.

You can fly in heaven, you don't have to die in heaven, you can be anywhere with anyone at your will in heaven, you can do anything in heaven perfectly.  You can create anything with your mind without taking from a planet, you are infinitely powerful in heaven.

You can own 22 million bitcoins in heaven.  You can live in any house, fall in love with any girl, be anyone, you're truly free.

Now why would you want to be restrained to finite life again?  Life's great.  But heaven is greater.  Heaven is perfect because you are in complete control.
