Something happened on that walk. I still felt the grief of loss that occupied the silences between the bustle of everyday life. But something else began to take over: a sense that it was all part of something bigger, that life and death and light and darkness were all one and essential and part of a broader cosmic unity. I miss my best friend, but I will carry with me all that we experienced together—until the day that I, too am gone. I hope to have letf behind some positive memories for others, as well, when my time comes. I also take with me, not only the memories, but an imperative—to live in such a way as to honor the memories of those lost along the way.
