Sri Uddhava-sandesa & Sri Hamsaduta
In a purport of Sri Caitanya-caritamrta, Srila Prabhupada has written: “In the Gaura-ganoddesa-dipika (180) Sri Rupa Gosvami is described to be the gopi named Sri Rupa-manjari. In the Bhakti-ratnakara there is a list of the books Sri Rupa Gosvami compiled. Of all his books, the following sixteen are very popular among Vaisnavas: (1) Hamsaduta, (2) Uddhava-sandesa, (3) Krsna-janma-tithi-vidhi, (4 and 5) Radha-krsna-ganoddesa-dipika, Brhta (major) and Laghu (minor), (6) Stavamala, (7) Vidagdha-madhava, (8) Lalita-madhava, (9) Dana-keli-kaumudi, (10) Bhakti-rasamrta-sindhu (this is the most celebrated book by Sri Rupa Gosvami), (11) Ujjvala-nilamani, (12) Akhyata-candrika, (13) Mathura-mahima, (14) Padyavali, (15) Nataka-candrika and (16) Laghu-bhagavatamrta.”
The subject of this wonderfully poetic book is how Krsna instructed Uddhava to go to Vrndavana and deliver a message to the residents there, who were suffering terribly the pangs of separation. This is nicely described by Srila Prabhupada in his book, KRSNA, The Supreme Personality of Godhead:
When Krsna was starting for Mathura on the chariot driven by Akrura and the gopis were blocking the way, Krsna assured them that He was coming back just after finishing His business in Mathura. He told them not to be overwhelmed and in this way pacified them.
