Pradyumna Brahmacari is described in the Antya-lila, Second Chapter, of Sri Caitanya-caritamrta. He was a great devotee of Lord Caitanya's who changed his name to Nrsimhananda. While coming from the house of Raghava Pandita at Panihati to the house of Sivananda, Lord Caitanya Mahaprabhu appeared in the heart of Nrsimhananda Brahmacari. To acknowledge this, Nrsimhananda Brahmacari used to accept as eatables the food of three Deities, namely, Jagannatha, Nrsimhadeva and Lord Caitanya Mahaprabhu. This is stated in the Caitanya-caritamrta, Antya-lila, Second Chapter, verses 48 through 78. Upon receiving information that Lord Caitanya Mahaprabhu was proceeding toward Vrndavana from Kuliya, Nrsimhananda absorbed himself in meditation and by his mental activities began constructing a very nice road from Kuliya to Vrndavana. All of a sudden, however, he broke his meditation and told the other devotees that this time Lord Caitanya Mahaprabhu would not go to Vrndavana but only as far as the place known as Kanai Natasala. This is described in the Madhya-lila, Chapter One, verses 155 through 162. The Gaura-ganoddesa-dipika, verse 74, says, avesas ca tathajneyo misre pradyumna-samjnake: Sri Caitanya Mahaprabhu changed the name of Pradyumna Misra, or Pradyumna Brahmacari, to Nrsimhananda Brahmacari, for in his heart Lord Nrsimhadeva was manifest. It is said that Lord Nrsimhadeva used to talk with him directly.
