Drawing on the ancient mystical text Sefer Yetsirah (the Book of Creation), Soloveitchik explains that the term refers neither to literal writing nor to mere narration, but to an injunction to parents to inscribe the story on the souls of their children—to “take a living person and turn him into a book.” (Video, Yiddish with English subtitles, 34 minutes.)
