Sri Caitanya-caritamrta

CC Adi-lila

Śrīvāsa Paṇḍita’s wife, Mālinī, is celebrated as an incarnation of the nurse Ambikā, who fed Lord Kṛṣṇa with her breast milk, and as already noted, his niece Nārāyaṇī, the mother of Ṭhākura Vṛndāvana dāsa, the author of Śrī Caitanya-bhāgavata, was the sister of Ambikā in kṛṣṇa-līlā. We also understand from the description of Śrī Caitanya-bhāgavata that after Lord Caitanya Mahāprabhu’s acceptance of the sannyāsa order, Śrīvāsa Paṇḍita left Navadvīpa, possibly because of feelings of separation, and domiciled at Kumārahaṭṭa.

CC Adi 10.8, Translation and Purport

The two brothers Śrīvāsa Paṇḍita and Śrī Rāma Paṇḍita started two branches that are well known in the world.

In the Gaura-gaṇoddeśa-dīpikā (90), Śrīvāsa Paṇḍita (Śrīvāsa Ṭhākura) is described as an incarnation of Nārada Muni, and Śrī Rāma Paṇḍita, his younger brother, is said to be an incarnation of Parvata Muni, a great friend of Nārada’s. Śrīvāsa Paṇḍita’s wife, Mālinī, is celebrated as an incarnation of the nurse Ambikā, who fed Lord Kṛṣṇa with her breast milk, and as already noted, his niece Nārāyaṇī, the mother of Ṭhākura Vṛndāvana dāsa, the author of Śrī Caitanya-bhāgavata, was the sister of Ambikā in kṛṣṇa-līlā. We also understand from the description of Śrī Caitanya-bhāgavata that after Lord Caitanya Mahāprabhu’s acceptance of the sannyāsa order, Śrīvāsa Paṇḍita left Navadvīpa, possibly because of feelings of separation, and domiciled at Kumārahaṭṭa.
