A. Rupa Goswami
Rupa Goswami appeared in 1489. Chief among the six Goswamis of Vrndavana who directly followed Lord Chaitanya, he was renowned as a great scholar and devotee of Lord Krishna. Together with his elder brother, Sanatana Goswami, he once served as a high-ranking officer under Hussain Shah. After meeting Lord Chaitanya, however, both brothers abandoned their posts to dedicate themselves to presenting Lord Chaitanya's teachings systematically by (1) uncovering Lord Krishna's lost places of pastimes; (2) installing Deities and establishing Their worship; (3) writing devotional literature; and (4) teaching the rules of bhakti-yoga, or devotional service. Srila Rupa Goswami wrote many books, including Bhakti-rasamrita-sindhu (“The Nectar of Devotion”), which gives the essence of all scriptures regarding bhakti-yoga. He left this world in 1564.
