I don’t like the idea of “understanding” a film. I don’t believe that rational understanding is an essential element in the reception of any work of art. Either a film has something to say to you or it hasn’t. If you are moved by it, you don’t need it explained to you. If not, no explanation can make you moved by it.
When we're true to ourselves, we become instruments of truth for the planet. Because we're all connected, we touch the lives of everyone around us, who then affect others. Our only obligation is to be the love we are and allow our answers to come from within in the way that's most appropriate for us.
