Here are the famous Govindam Prayers from the Brahma-samhita, the glorification of Sri Krsna that Lord Brahma sang when the Lord revealed Himself to Brahma at the dawn of the universe. The Krsna-karnamrta, by Bilvamangala Thakura, was one of Lord Caitanya’s favorite works. He would often listen to his secretary, Svarupa Damodara Gosvami, chant verses from the Karnamrta during the latter portion of His pastimes, in Jagannatha Puri. The poetry of the Karnamrta is unsurpassed in Vaishnava annals; it is recognized as a classic of Vaisnava literature. Lord Caitanya discovered these two books on His tour of South India, and He eagerly had them copied so He could take them back to Puri and share them with all the devotees there, who greatly relished them.
Translations of the Brahma-samhita are by Srila Bhaktisiddhanta Sarasvati Thakura and Srila Prabhupada; the translations of the Krsna-karnamrta are by Dravida dasa.
