According to some authoritative opinions, although Keśava Bhāratī belonged to the Śaṅkara-sampradāya, he had formerly been initiated by a Vaiṣṇava. He is said to have been a Vaiṣṇava on account of having been initiated by Mādhavendra Purī, for some say that he took sannyāsa from Mādhavendra Purī. The temple and Deity worship started by Keśava Bhāratī are still existing in the village known as Khāṭundi, which is under the postal jurisdiction of Kāndarā in the district of Burdwan.

CC Adi 9.13-15, Translation and Purport

Paramānanda Purī, Keśava Bhāratī, Brahmānanda Purī and Brahmānanda Bhāratī, Śrī Viṣṇu Purī, Keśava Purī, Kṛṣṇānanda Purī, Śrī Nṛsiṁha Tīrtha and Sukhānanda Purī—these nine sannyāsī roots all sprouted from the trunk of the tree. Thus the tree stood steadfastly on the strength of these nine roots.

“Śrī Caitanya Mahāprabhu used to say, ‘I am living in this world only on account of the excellent behavior of Śrī Paramānanda Purī.’” The Gaura-gaṇoddeśa-dīpikā (118) states, purī śrī-paramānando ya āsīd uddhavaḥ purā. “Paramānanda Purī is none other than Uddhava.” Uddhava was Lord Kṛṣṇa’s friend and cousin, and in caitanya-līlā the same Uddhava became the friend of Śrī Caitanya Mahāprabhu and His uncle in terms of their relationship in the disciplic succession.

Keśava Bhāratī: The Sarasvatī, Bhāratī and Purī sampradāyas belong to the Śṛṅgerī-maṭha in South India, and Śrī Keśava Bhāratī, who at that time was situated in a monastery in Katwa, belonged to the Bhāratī-sampradāya. According to some authoritative opinions, although Keśava Bhāratī belonged to the Śaṅkara-sampradāya, he had formerly been initiated by a Vaiṣṇava. He is said to have been a Vaiṣṇava on account of having been initiated by Mādhavendra Purī, for some say that he took sannyāsa from Mādhavendra Purī. The temple and Deity worship started by Keśava Bhāratī are still existing in the village known as Khāṭundi, which is under the postal jurisdiction of Kāndarā in the district of Burdwan. According to the managers of that maṭha, the priests are descendants of Keśava Bhāratī, and some say that the worshipers of the Deity are descendants of the sons of Keśava Bhāratī. In his householder life he had two sons, Niśāpati and Ūṣāpati, and a brāhmaṇa of the name Śrī Nakaḍicandra Vidyāratna, who was a member of the family of Niśāpati, was the priest in charge at the time that Śrī Bhaktisiddhānta Sarasvatī visited this temple. According to some, the priests of the temple belong to the family of Keśava Bhāratī’s brother. Still another opinion is that they descend from Mādhava Bhāratī, who was another disciple of Keśava Bhāratī’s. Mādhava Bhāratī’s disciple Balabhadra, who also later became a sannyāsī of the Bhāratī-sampradāya, had two sons in his family life, named Madana and Gopāla. Madana, whose family’s surname was Bhāratī, lived in the village of Āuriyā, and Gopāla, whose family’s surname was Brahmacārī, lived in the village of Denduḍa. There are still many living descendants of both families.
