No heaven no hell - It's here and now. Living for today
No countries (governments) no relegion. Nothing to kill or die for - we could actually live in peace
No possesions no greed - no more keeping up with the Jones. We can help our fellow man, rather than put ourselves above them because of the how much we have.
This is not communism. You need a government to take care of you.
This is an ideal of people living with people and accepting all people as equals.
Since we live our lives in our minds, this is all very do able. All we have to do is think it so.
