Śrī Rāmadāsa, later known as Abhirāma Ṭhākura, was one of the twelve gopālas, cowherd boyfriends, of Śrī Nityānanda Prabhu. The Gaura-gaṇoddeśa-dīpikā, verse 126, states that Śrī Rāmadāsa was formerly Śrīdāmā. In Bhakti-ratnākara (Fourth Wave), there is a description of Śrīla Abhirāma Ṭhākura. By the order of Śrī Nityānanda Prabhu, Abhirāma Ṭhākura became a great ācārya and preacher of the Caitanya cult of devotional service. He was a very influential personality, and non-devotees were very afraid of him. Empowered by Śrī Nityānanda Prabhu, he was always in ecstasy and was extremely kind to all fallen souls. It is said that if he offered obeisances to any stone other than a śālagrāma-śilā, it would immediately fracture.
The temple of Abhirāma Ṭhākura is situated in Kṛṣṇanagara, which is near the kūla (bank) of the Khānā (Dvārakeśvara River); therefore this place is celebrated as Khānākūla-kṛṣṇanagara. Outside of the temple is a bakula tree. This place is known as Siddha-bakula-kuñja. It is said that when Abhirāma Ṭhākura came there, he sat down under this tree. The temple of Abhirāma Ṭhākura has a very old history. The Deity in the temple is known as Gopīnātha. There are many sevaite families living near the temple. It is said that Abhirāma Ṭhākura had a whip and that whoever he touched with it would immediately become an elevated devotee of Kṛṣṇa.
