Thich Thanh Van was killed during his effort to help other people. He was a good Buddhist, he was a good Buddha, because he was able to help tens of thousands of people, victims of the war. Because of him, awakening, understanding, and love were real things. So we can call him a Buddha body, in Sanskrit Buddhakaya. For Buddhism to be real, there must be a Buddhakaya, an embodiment of awakened activity. Otherwise Buddhism is just a word.
