Rupa Goswami - "The one who knows the essence of devotional service"

"...This year, August 19th 2021 is the disappearance day of Srila Rüpa Gosvami, one of the most confidential disciples of Sri Caitanya Mahäprabhu. Srila Rupa Gosvami is described as the bhakti-rasacarya, or one who knows the essence of devotional service. His famous book Bhakti-rasamrta-sindhu is the science of devotional service, and by reading this book one can understand the meaning of devotional service. Srila Rupa Gosvami describes in his Bhakti-rasamata-sindhu that devotional service is so exalted that it is beneficial and auspicious for every person..."
Sri Caitanya Mahäprabhu directly taught Srila Rüpa Gosvami for more than ten days continually and instructed him to revive the holy sites of Krishna’s pastimes in Vrindavana and to write books establishing the authenticity of Krishna consciousness.
