Śrī Kānu Ṭhākura, a very respectable gentleman, was the son of Puruṣottama dāsa Ṭhākura. He was such a great devotee that Lord Kṛṣṇa always lived in his body.
Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura writes in his Anubhāṣya, “To go to the headquarters of Kānu Ṭhākura, one has to proceed by boat from the Jhikaragāchā-ghāṭa station to the river known as Kapotākṣa. Otherwise, if one goes about two or two and a half miles from the Jhikaragāchā-ghāṭa station, he can see Bodhakhānā, the headquarters of Kānu Ṭhākura. The son of Sadāśiva was Puruṣottama Ṭhākura, and his son was Kānu Ṭhākura. The descendants of Kānu Ṭhākura know him as Nāgara Puruṣottama. He was the cowherd boy named Dāma during kṛṣṇa-līlā. It is said that just after the birth of Kānu Ṭhākura, his mother, Jāhnavā, died. When he was about twelve days old, Śrī Nityānanda Prabhu took him to His home at Khaḍadaha. It is ascertained that Kānu Ṭhākura was born some time in the Bengali year 942 [A.D. 1535]. It is said that he took birth on the Ratha-yātrā day. Because he was a great devotee of Lord Kṛṣṇa from the very beginning of his life, Śrī Nityānanda Prabhu gave him the name Śiśu Kṛṣṇadāsa. When he was five years old he went to Vṛndāvana with Jāhnavā-mātā, and the Gosvāmīs, upon seeing the ecstatic symptoms of Kānu Ṭhākura, gave him the name Kānāi Ṭhākura.
“In the family of Kānu Ṭhākura there is a Rādhā-Kṛṣṇa Deity known as Prāṇavallabha. It is said that his family worshiped this Deity long before the appearance of Lord Caitanya Mahāprabhu. When there was a Maharashtrian invasion of Bengal, the family of Kānu Ṭhākura was scattered, and after the invasion one Harikṛṣṇa Gosvāmī of that family came back to their original home, Bodhakhānā, and re-established the Prāṇavallabha Deity. The descendants of the family still engage in the service of Prāṇavallabha. Kānu Ṭhākura was present during the Kheṭari utsava, when Jāhnavā-devī and Vīrabhadra Gosvāmī were also present. One of Kānu Ṭhākura’s family members, Mādhavācārya, married the daughter of Śrī Nityānanda Prabhu, who was named Gaṅgādevī. Both Puruṣottama Ṭhākura and Kānu Ṭhākura had many disciples from brāhmaṇa families. Most of the disciplic descendants of Kānu Ṭhākura now reside in the village named Gaḍabetā, by the river Śilāvatī, in the Midnapore district.”
