Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura writes in his Anubhāṣya, “Sadāśiva Kavirāja and Nāgara Puruṣottama, who were father and son, are described in the Caitanya-bhāgavata as mahā-bhāgyavān, greatly fortunate. They belonged to the vaidya caste of physicians. text 156 of the Gaura-gaṇoddeśa-dīpikā says that Candrāvalī, a most beloved gopī of Kṛṣṇa’s, later took birth as Sadāśiva Kavirāja. In texts 194 and 200 it is said that Kaṁsāri Sena, the father of Sadāśiva Kavirāja, was formerly the gopī named Ratnāvalī in Kṛṣṇa’s pastimes. All the family members of Sadāśiva Kavirāja were great devotees of Lord Caitanya Mahāprabhu. Puruṣottama dāsa Ṭhākura sometimes lived at Sukhasāgara, near the Cākadaha and Śimurāli railway stations. All the Deities installed by Puruṣottama Ṭhākura were formerly situated in Beleḍāṅgā-grāma, but when the temple was destroyed the Deities were brought to Sukhasāgara. When that temple merged into the bed of the Ganges, the Deities were brought with Jāhnavā-mātā’s Deity to Sāhebaḍāṅgā Beḍigrāma. Since that place also has been destroyed, all the Deities are now situated in the village named Cānduḍe-grāma, which is situated one mile up from Pālapāḍā, as referred to above.”
