Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura writes in his Anubhāṣya, “The Caitanya-bhāgavata states that Parameśvara dāsa, known sometimes as Parameśvarī dāsa, was the life and soul of Śrī Nityānanda Prabhu. The body of Parameśvara dāsa was the place of Lord Nityānanda’s pastimes. Parameśvara dāsa, who lived for some time at Khaḍadaha village, was always filled with the ecstasy of a cowherd boy. Formerly he was Arjuna, a friend of Kṛṣṇa and Balarāma. He was the fifth among the twelve gopālas. He accompanied Śrīmatī Jāhnavā-devī when she performed the festival at Khetari. It is stated in the Bhakti-ratnākara that by the order of Śrīmatī Jāhnavā-mātā, he installed Rādhā-Gopīnātha in the temple at Āṭapura, in the district of Hugli. The Āṭapura station is on the narrow-gauge railway line between Howrah and Āmatā. Another temple in Āṭapura, established by the Mitra family, is known as the Rādhā-Govinda temple. In front of the temple, in a very attractive place among two bakula trees and a kadamba tree, is the tomb of Parameśvarī Ṭhākura, and above it is an altar with a tulasī bush. It is said that only one flower a year comes out of the kadamba tree. It is offered to the Deity.

“Parameśvarī Ṭhākura belonged, it is said, to a vaidya family. A descendant of his brother’s is at present a worshiper in the temple. Some of their family members still reside in the district of Hugli, near the post office of Caṇḍītalā. The descendants of Parameśvarī Ṭhākura took many disciples from brāhmaṇa families, but as these descendants gradually took to the profession of physicians, persons from brāhmaṇa families ceased becoming their disciples. The family titles of Parameśvarī’s descendants are Adhikārī and Gupta. Unfortunately, his family members do not worship the Deity directly; they have engaged paid brāhmaṇas to worship the Deity. In the temple, Baladeva and Śrī Śrī Rādhā-Gopīnātha are together on the throne. It is supposed that the Deity of Baladeva was installed later because according to transcendental mellow, Baladeva, Kṛṣṇa and Rādhā cannot stay on the same throne. On the full-moon day of Vaiśākha (April-May), the disappearance festival of Parameśvarī Ṭhākura is observed in this temple.”
