In the introduction to his 11th century book Duties of the Heart, R. Bahya Ibn Pakuda poses a question that Jewish educators continue to struggle with today. Bahya asks why he cannot find any source in rabbinic texts that describes the inner life of the Jew. He knows there are mitzvot to learn and perform, he knows that there are intellectual concepts to attain and reason with but where are, what he calls, “The Duties of the Heart?” The book that he writes, one of the most popular Jewish books for 1000 years, starts to enumerate these Duties and weighs them alongside the mitzvot and de’ot, what he identifies as the “Duties of the Limbs.”
