Sivananda Sen had three sons: Sri Caitanya dasa, Sri Rama dasa and Paramananda. The guru of Paramananda was Sri Natha Pandita who was the disciple of Advaita Acarya. In the beginning of Sri Ananda Vrindavana Campu, Kavi Karnapura has offered prayers to his Sri Gurudeva, who resided at Kanca Para, one and a half miles from Kumar Hatta. His Deity of Sri Krsna Raya is still residing there. The 'Kesto Ray' temple can be reached by ricksaw from either Kanca Para railstarion or from Halisahar.
In his Gaur-ganoddesa-dipika, Kavi Karnapura states, "He who was previously known as the gopi Bira and who was the messenger (duti) of Radharani, has now become my father, Sivananda Sen." After spending the four months of the rainy season (Caturmasya) with Mahaprabhu, the devotees were preparing to return to Bengal. At that time, Mahaprabhu called Sivananda and told him, "You should name your next son Puri das."
Having received that benediction, Sivananda very joyfully proceeded on the way back to his home. A few months later a son was born to him and after consulting with an astrologer the boy was named Paramananda dasa. (What happened to Puri dasa?)
The following year Sivananda again brought the devotees, along with his wife and new born son, to Puri, to see Mahaprabhu. Sivananda induced his son to offer his dandavats at the lotus feet of Prabhu and thus placed him at His lotus feet. The boy was simply looking at the lotus feet of Mahaprabhu, who laughed gently and placed His foot in front of the baby. Then the child in great ecstasy, caught hold of Prabhus foot with both hands, and began to suck on His toe, while the devotees resounded in joy, "Hari! Hari!" This boy later became known as Sri Kavi Karnapura Gosvami.
One day Sivananda brought his son Puri das with him to see Mahaprabhu. The boy offered his obeisances at the lotus feet of Prabhu at which Prabhu addressed him, "Puri das! Let me hear you recite something." The boy replied, "Svavasoh kuvaloy maksemaranja namuraso mahendra mani dam vrindavan ramaninam mandanama khilam harir jayati." (Which means?)
Everyone was astonished that a seven year old boy, with no education could recite sanskrit verses. All the devotees remarked that surely he has received the Lord's mercy. Mahaprabhu was moved to ecstasy by hearing this verse and embraced the boy in great love, showering His blessings upon him, "May you always be enlivened in the ecstasy of Krsna's pastimes."
Svarupa Damodara remarked "This verse that he has recited is the prime object of satisfation for the ears of the devotees. Therefore one of his names will be Karnapura." (But why?) Thus the son of Sivananda later became famous as Kavi Karnapur.
He compiled following literatures: Caitanya-candrodaya-nataka, Ananda- vrindavana-campu, Caitanyamrta Mahakavya, Gaura-ganoddesa-dipika, Radha-Krsna-ganoddesa-dipika, Sri Krsna-chika-kaumadi, Alankara-kaustubha, Arya-sataka.
