As writers themselves, you'd think that the Kellers would appreciate the power of writing as a process for understanding life and coming to terms with painful experiences. Writing is a powerful way of connecting with others. Writing helps us reach inward -- and upward -- to find the holy, the numinous, the transcendent.
In my mind, the film is about transcending gravity; the quest to live life a few feet off the ground. The Kaballah teaches that growth and impact emerge from living outside our comfort zone. The ground offers security but the most memorable moments in life and fulfillment arise when we strive to live a little higher and brighter.
