In a purport of the Caitanya-caritamrta, Srila Prabhupada wrote: Srila Rupa Gosvami is described as the bhakti-rasacarya, or one who knows the essence of devotional service. His famous book Bhakti-rasamtra-sindhu is the science of devotional service, and by reading this book one can understand the meaning of devotional service. Another of his famous books is the Ujjvala-nilamani. In this book he elaborately explains the loving affairs and transcendental activities of Lord Krsna and Radharani.
We should very carefully understand the exalted position of this book and also appreciate the qualification that are required for hearing it.
