Despite lies, mind manipulation, biased media, controlled prejudices, all people everywhere ultimately want peace, even if it is for oneself alone.
It's easy for me to imagine a world without the need for money. Earth provides everything necessary for its inhabitants to live and prosper freely. Talents are for sharing not to profit.
And diversity is the greatest gift.
It doesn't matter how one thinks to achieve peace differs from another.
Differing thoughts can achieve the same means/peace. Once peace is attained, no one will care that someone else thought their way to peace differently.
It should be easy enough to imagine heaven as stress free. When everyone wins their quest for peace, heaven on earth will exist. Stress free living will exist. Pure peace will exist.
