The three sons of Śivānanda Sena, named Caitanya dāsa, Rāmadāsa and Karṇapūra, were all heroic devotees of Lord Caitanya.

Caitanya dāsa, the eldest son of Śivānanda Sena, wrote a commentary on Kṛṣṇa-karṇāmṛta that was later translated by Śrīla Bhaktivinoda Ṭhākura in his paper Sajjana-toṣaṇī. According to expert opinion, Caitanya dāsa was the author of the book Caitanya-carita (also known as Caitanya-caritāmṛta), which was written in Sanskrit. The author was not Kavi-karṇapūra, as is generally supposed. This is the opinion of Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura. Śrī Rāmadāsa was the second son of Śivānanda Sena. It is stated in the Gaura-gaṇoddeśa-dīpikā (145) that the two famous parrots named Dakṣa and Vicakṣaṇa in kṛṣṇa-līlā became the elder brothers of Kavi-karṇapūra, namely Caitanya dāsa and Rāmadāsa. Karṇapūra, the third son, who was also known as Paramānanda dāsa or Purī dāsa, was initiated by Śrīnātha Paṇḍita, who was a disciple of Śrī Advaita Prabhu. Karṇapūra wrote many books that are important in Vaiṣṇava literature, such as the Ānanda-vṛndāvana-campū, Alaṅkāra-kaustubha, Gaura-gaṇoddeśa-dīpikā and the great epic Caitanya-candrodaya-nāṭaka.
