The twenty-third and twenty-fourth prominent devotees of Nityänanda Prabhu were Sadäçiva Kaviräja and his son Puruñottama däsa, who was the tenth gopäla. From birth, Puruñottama däsa was merged in the service of the lotus feet of Lord Nityänanda Prabhu, and he always engaged in childish play with Lord Kåñëa. Çré Känu Öhäkura, a very respectable gentleman, was the son of Puruñottama däsa Öhäkura. He was such a great devotee that Lord Kåñëa always lived in his body.
– (Chaitanya Charitamrita Adi 11.38-40)
“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, later took birth as Sadasiva Kaviraja, who was a great devotee 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 Beledana-grama, but when the temple was destroyed, the Deities were brought to Sukhasagara. When that temple merged in the bed of the Ganges, the Deities were brought with Janava-mata’s Deity to Sahebasanga Bedigrama. Since that place also has been destroyed, all the Deities are now situated in the village named Candudegrama, which is situated one mile up from Palapada, as referred to above.”
(Anubhāṣya, by Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura)
For four generations the family of Purushottam Das consisted of eternally perfect direct associates of Mahaprabhu: Kamsari Sen, Sadashiva Kaviraj, Purushottam Thakura, and Kanu Thakur. The Gaura-ganodesa-dipika identifies Kamsari Sen as Ratnavali Sakhi and Sadashiva Kaviraj as Chandravali (156). Sri Purusottama Thakura was the cowherd boy named Stoka-krsna in Krisna-lila. Kanu Thakura was the cowherd boy named Däma during kåñëa-lélä.
His samadhi is located in the 64 Samadhis Area.
