Purushottama dasa was Stoka Krishna, the cowherd boy in Krishna lila.
From the time he was a small boy, Purushottama dasa Thakura was dedicated to constantly meditating on the lotus feet of Shri Nityananda Prabhu.
CC Adi 11.38: The twenty-third and twenty-fourth prominent Devotees of Nityananda Prabhu were Sadashiva Kaviraja and his son Purushottama dasa, who was the tenth gopala.
CC Adi 11.39: From birth, Purushottama dasa was merged in the service of the lotus feet of Lord Nityananda Prabhu, and he always engaged in childish play with Lord Krishna.
CC Adi 11.40: Shri Kanu Thakura, a very respectable gentleman, was the son of Purushottama dasa Thakura. He was such a great Devotee that Lord Krishna always lived in his body.
C.B. Antya 5 Text 742: External consciousness was never present in Purushottama dasa's body. In his heart Lord Nityananda always enjoyed pastimes.
Shri Bhaktivedanta Swami writes: "Sadashiva Kaviraja and Nagara Purushottama, who were father and son, are described in the Chaitanya-Bhagavata as maha-bhagyavan, greatly fortunate. They belonged to the vaidya caste of physicians."
Shri Purushottama Thakura had three main disciples: Shri Madhavacharya, Shri Yadavacharya and Devakinandana dasa, who were born in Kulina brahmana families. Madhavacharya married Nityananda Prabhu's daughter, Ganga-devi. Devakinandana was the author of the book Vaishnav-vandane.
Purushottama Thakura's Shripat was previously at Sukhasagara. When Sukhasagar sank into the Ganges, Kanu Thakura carried the Deity of Pranavallabha and brought his father to Bodhakhana. The Deity was served at Bodhakhana till 1950 A.D. when political upheaval in Pakistan resulted in the shifting of the Deity to Jadavpur Ghospada in the district twenty-four Parganas at the house of Gaurahari Goswami, a descendant of Kanu Thakura.
Purushottama dasa Thakura's wife's name was Jahnava. She passed away just after bearing Purushottama dasa Thakura's son Kanu. Hearing this news, Nityananda Prabhu went to the house of Purushottama dasa Thakura and took his son Kanu with him to his own village of Khandaha.
