I'm not sure about this one. I think the math is off. Not really sure what I was thinking at the time. I suppose the infinite symbol and how it applies to a relationship. I think the reason why the word "ONE" is in caps is because when the two individual souls cease being individuals and merge to become one soul. The the souls become mated or married.
Imagine the infinite symbol. To the right or left you have what can be thought of as male and female, right and wrong, more or less, and etc. But, in the absolute middle you have the joining or connection.
