Uddhava was Krishna's cousin who resembled him in complexion and other features. He was the foremost devotee of the Lord. In fact, Krishna chose him as his emissary to convey his message of solace and courage to his parents and the Gopikas at Vraja, since they were feeling restless and despondent after he left for Mathura with Akrura.
The ‘Uddhava Gita' incorporates the teachings of Lord Krishna to Uddhava given on the eve of His departure to His heavenly abode and it forms part of the Bhagavata Purana. Quite befittingly christened Krishna's Other Song by Steven Rosen, it is a very popular philosophical text known to the orthodox Hindu tradition. It is, however, lesser known than the Bhagavad Gita, which contains the Lord's teachings to Arjuna on the Kurukshetra battlefield.
In the book under review Rosen, a votary of ‘Krishna Consciousness', gives a very lucid and simple translation of the 1,030-verse Sanskrit text, without “labouring to translate each word verbatim.” However, he does not provide the original text.
The ‘Uddhava Gita' picks up where the ‘Bhagavad Gita' leaves off. There are a few points common between the two; for instance, both lay stress on everyone doing one's duty without thinking of the results, and on the omnipresence of God.
