Sogyal Rinpoche’s sentence carries an endnote, and the book keeps that citation in later editions. But readers quoting the line rarely carried the endnote with it. Within two years, according to Zitatforschung, the sentence was appearing in quotation marks as Rilke’s own words with no mention of the book it came from — among the instances it cites are Dawna Markova’s No Enemies Within (Conari Press, 1994) and Caitlin Matthews’ Singing the Soul Back Home (Element, 1995).
Music and television did the rest. Ray Wylie Hubbard, who has said repeatedly that Letters to a Young Poet changed his life, closed “The Messenger” on his 1994 album Loco Gringo’s Lament with the same fear-as-dragon-over-treasure image, credited to Rilke. And in 2021 the line turned up on a dating app in Ted Lasso, where Rebecca reads it out as Rilke and Keeley approves.
German-language versions were re-translated back out of Rinpoche’s English rather than from anything Rilke wrote, which is why the German circulating text (“Unsere größten Ängste sind die Drachen, die unsere tiefsten Schätze bewahren”) matches no line in Rilke’s collected letters.
