According to Gaura-gaṇoddeśa-dīpikā (126), Sri Ramadasa was formerly Sridama, one of the cowherd associates of Krishna. In the Bhakti-ratnakara (Fourth Wave), there is a detailed description of Sri Abhirama Thakura.
By the order of Sri Nityananda Prabhu, Abhirama Thakura became a great acharya and preacher of the Chaitanya movement. He was a very influential personality, and nondevotees were very much afraid of him. He was always in ecstasy and was extremely kind to fallen souls.
