Love is the most powerful force in the universe. I believe this unironically, and not in a woo-woo kind of way.
Love compels people to make the world better, but it can also compel people to do horrible things.
I see love like an energy field that extends outward from people.
Some people have a very small love field, they only love themselves.
Some people have a moderate size, they love themselves and their family.
Other people have love for everyone. Their love energy field is quite large.
It's like a sliding scale representing the number of people you care about.
