We always write stories of tragedies because that's how we reach our human depth. How we get to the other side of it. We look at the cruelty, the darkness and horrific events that happened in our life whether it be a miscarriage or a husband who is not faithful. Then you find this ability to transcend. And that is called the passion, like the passion of Christ. You could call this the passion of Frida Kahlo, in a way.
When I talk about passion, and I'm not a religious person, but I absolutely am drawn and attracted to the power of religious art because it gets at that most extreme emotion of the human experience.
