A short history of the Narada Bhakti Sutra:In 1967, His Divine Grace A.C. Bhaktivedanta Swami Prabhupada translated and wrote purports for thirteen of the eighty-four aphorisms (Srila Prabhupada called them �codes�) of the Narada-Bhakti-Sutra.In 1989, at the annual GBC meeting, they suggested, that Satsvarupa and Gopiparanadhana Prabhu complete this Narada-bhakti-Sutra. They were happy to accept the assignment, especially because of Satsvarupa�s involvement with Srila Prabhupada�s initial writing of the Narada-bhakti-sutra
