"Đức calmly sat down in the traditional Buddhist meditative lotus position on the cushion. A colleague emptied the contents of the petrol container over Đức's head. Đức rotated a string of wooden prayer beads and recited the words Nam mô A Di Đà Phật ("Homage to Amitābha Buddha") before striking a match and dropping it on himself."
"Photographs of his self-immolation were circulated widely across the world and brought attention to the policies of the Diệm government. John F. Kennedy said in reference to a photograph of Đức on fire, "No news picture in history has generated so much emotion around the world as that one.""
