I have never seen an expression as full of wonder as Lou’s as he died. His hands were doing the water-flowing 21-form of tai chi. His eyes were wide open. I was holding in my arms the person I loved the most in the world, and talking to him as he died. His heart stopped. He wasn’t afraid. I had gotten to walk with him to the end of the world. Life—so beautiful, painful and dazzling—does not get better than that. And death? I believe that the purpose of death is the release of love.
