In my head, I had sort of justified it all by saying human beings break down to three categories: You’ve got circles, squares and triangles. Squares are people that are neutral. They live life by knowledge and logic and scientific approach to finding information and truth, and they build people very practical things. So if you go to a square and say, “I’m homeless,” he’ll build you a building. He won’t think anything past that. Squares give us the tools and shelter and grids and roads and blah, blah, blah. And then you have the triangles, who are people that are led by power and money and ego. These things all work on a pyramid structure: You have one person at the top and billions at the bottom. And then you have the circles, who are just led by love. The concept of the universe is built on circles. I think evolution is built on a circular sort of shape, and any natural organisms have circular things in common: If you cut a tree you get circles, natural disasters happen in circular forms, and the planets are circles, our eyes are circles.
