There's something about world peace that feels very 'Brave New World'. World peace but at what cost? Our individual sovereignty? I get similar feels from those who would have us believe we need to assend by surrendering to the God entity.
I experience internal peace, peace within. That peace requires no other entity to conform to my beliefs. I do not have to wait to experience it, I can find it & experience it whenever I chose to.
Know that you can take the life of another while your heart is filled with love for them. Don't ever do it from fear or ego though.
