From birth, Purusottama dasa was merged in the service of the lotus feet of Lord Nityananda Prabhu, and he always engaged in childish play with Lord Krsna.
Sadasiva Kaviraja and Nagara Purusottama, who were father and son, are described in the Caitanya-bhagavata as maha-bhagyavan, greatly fortunate. They belonged to the vaidya caste of physicians. The Gaura-ganoddesa-dipika, verse 156, says that Candravali, a most beloved gopi of Krsna's, later took birth as Sadasiva Kaviraja. In verses 194 and 200 it is said that Kamsari Sena, the father of Sadasiva Kaviraja, was formerly the gopi named Ratnavali in Krsna's pastimes. All the family members of Sadasiva Kaviraja were great devotees of Lord Caitanya Mahaprabhu. Purusottama dasa Thakura sometimes lived at Sukhasagara, near the Cakadaha and Simurali railway stations. All the Deities installed by Purusottama Thakura were formerly situated in Beledanga-grama, but when the temple was destroyed the Deities were brought to Sukhasagara. When that temple merged into the bed of the Ganges, the Deities were brought with Jahnava-mata's Deity to Sahebadanga Bedigrama. Since that place also has been destroyed, all the Deities are now situated in the village named Candude-grama, which is situated one mile up from Palapada, as referred to above.
