The thirteenth branch was Pradyumna Brahmacārī. Since he was a worshiper of Lord Nṛsiṁhadeva, Śrī Caitanya Mahāprabhu changed his name to Nṛsiṁhānanda Brahmacārī.
Pradyumna Brahmacārī is described in the Antya-līlā, Second Chapter, of Śrī Caitanya-caritāmṛta. He was a great devotee of Lord Caitanya, who changed his name to Nṛsiṁhānanda. While coming from the house of Rāghava Paṇḍita at Pānihāṭi to the house of Śivānanda, Lord Caitanya Mahāprabhu appeared in the heart of Nṛsiṁhānanda Brahmacārī. To acknowledge this, Nṛsiṁhānanda Brahmacārī used to accept as eatables the food of three Deities, namely Jagannātha, Nṛsiṁhadeva and Lord Caitanya Mahāprabhu. This is stated in the Caitanya-caritāmṛta, Antya-līlā, Second Chapter, verses 48 through 78. Upon receiving information that Lord Caitanya Mahāprabhu was proceeding toward Vṛndāvana from Kuliyā, Nṛsiṁhānanda absorbed himself in meditation and by his mental activities began constructing a very nice road from Kuliyā to Vṛndāvana. All of a sudden, however, he broke his meditation and told the other devotees that this time Lord Caitanya Mahāprabhu would not go to Vṛndāvana but would travel only as far as the place known as Kānāi Nāṭaśālā. This is described in Madhya-līlā, Chapter One, verses 155 through 162. The Gaura-gaṇoddeśa-dīpikā (74) says, āveśaś ca tathājñeyo miśre pradyumna-saṁjñake: Śrī Caitanya Mahāprabhu changed the name of Pradyumna Miśra, or Pradyumna Brahmacārī, to Nṛsiṁhānanda Brahmacārī, for in his heart Lord Nṛsiṁhadeva was manifest. It is said that Lord Nṛsiṁhadeva used to talk with him directly.
The former Pradyumna Brahmacārī was given the name Nṛsiṁhānanda Brahmacārī by Śrī Caitanya Mahāprabhu.
In the Gaura-gaṇoddeśa-dīpikā (73–74) it is said that Nakula Brahmacārī displayed the prowess (āveśa) and Pradyumna Brahmacārī the appearance (āvirbhāva) of Śrī Caitanya Mahāprabhu. There are many hundreds and thousands of devotees of Lord Caitanya among whom there are no special symptoms, but when a devotee of Lord Śrī Caitanya Mahāprabhu functions with specific prowess, he displays the feature called āveśa. Śrī Caitanya Mahāprabhu personally spread the saṅkīrtana movement, and He advised all the inhabitants of Bhāratavarṣa to take up His cult and preach it all over the world. The visible bodily symptoms of devotees who follow such instructions are called āveśa. Śrīla Śivānanda Sena observed such āveśa symptoms in Nakula Brahmacārī, who displayed symptoms exactly like those of Śrī Caitanya Mahāprabhu. The Caitanya-caritāmṛta states that in the Age of Kali the only spiritual function is to broadcast the holy name of the Lord, but this function can be performed only by one who is actually empowered by Lord Kṛṣṇa. The process by which a devotee is thus empowered is called āveśa, or sometimes it is called śakty-āveśa.
Pradyumna Brahmacārī was formerly a resident of a village known as Piyārīgañja in Kālnā. There is a description of him in the Antya-līlā of Śrī Caitanya-caritāmṛta, Second Chapter, and in the Antya-khaṇḍa of Śrī Caitanya-bhāgavata, chapters Three and Nine.
When Śrī Nṛsiṁhānanda Brahmacārī heard that Lord Caitanya Mahāprabhu would go to Vṛndāvana, he became very pleased and mentally began decorating the way there.
First Nṛsiṁhānanda Brahmacārī contemplated a broad road starting from the city of Kuliyā. He bedecked the road with jewels, upon which he then laid a bed of stemless flowers.
Within the mind of Nṛsiṁhānanda Brahmacārī, the road could not be constructed beyond Kānāi Nāṭaśālā. He could not understand why the road's construction could not be completed, and thus he was astonished.
Śrīla Nṛsiṁhānanda Brahmacārī was a great devotee of Lord Caitanya Mahāprabhu; therefore when he heard that from Kuliyā Śrī Caitanya Mahāprabhu was going to Vṛndāvana, although he had no material wealth he began to construct within his mind a very attractive path or road for Caitanya Mahāprabhu to traverse. Some of the description of this path is given above. But even mentally he could not construct the road beyond Kānāi Nāṭaśālā. Therefore he concluded that Caitanya Mahāprabhu would not go to Vṛndāvana at that time.
Nṛsiṁhānanda Brahmacārī said, "The Lord will go to Kānāi Nāṭaśālā and then will return. All of you will come to know of this later, but I now say this with great assurance."
Śrī Caitanya Mahāprabhu delivered almost all the fallen souls by directly meeting them. He delivered others by entering the bodies of great devotees, such as Nakula Brahmacārī. And He delivered still others by appearing before them, as in the case of Nṛsiṁhānanda Brahmacārī. "I shall deliver the fallen souls." This statement characterizes the Supreme Personality of Godhead.
Śrī Caitanya Mahāprabhu appeared before Nṛsiṁhānanda Brahmacārī and ate his offerings. Please hear about this with attention.
Hearing this, Nṛsiṁhānanda Brahmacārī replied, "Please be satisfied. I assure you that I shall bring Him here three days from now."
Śivānanda and Jagadānanda knew of Nṛsiṁhānanda Brahmacārī’s influence and love of Godhead. Therefore they now felt assured that he would certainly bring Śrī Caitanya Mahāprabhu.
His real name was Pradyumna Brahmacārī. The name Nṛsiṁhānanda had been given to him by Lord Gaurasundara Himself.
After meditating for two days, Nṛsiṁhānanda Brahmacārī told Śivānanda Sena, "I have already brought Śrī Caitanya Mahāprabhu to the village known as Pāṇihāṭi."
Nṛsiṁhānanda Brahmacārī said to Śivānanda, "Please bring whatever cooking ingredients I want." Thus Śivānanda Sena immediately brought whatever he asked for.
Beginning early in the morning, Nṛsiṁhānanda Brahmacārī cooked many varieties of food, including vegetables, cakes, sweet rice and other preparations.
Pradyumna Brahmacārī was overwhelmed by transcendental ecstasy upon seeing Caitanya Mahāprabhu eating everything. Thus tears flowed from his eyes. Nevertheless, he expressed dismay, saying, "Alas, alas! My dear Lord, what are You doing? You are eating everyone's food!"
Pradyumna Brahmacārī was deeply eager to understand this fact. Therefore Śrī Caitanya Mahāprabhu revealed it to him by a practical demonstration.
When Śivānanda Sena heard this statement, he was unsure whether Nṛsiṁhānanda Brahmacārī was speaking that way because of ecstatic love or because it was actually a fact.
When Śivānanda Sena was thus perplexed, Nṛsiṁhānanda Brahmacārī said to him, "Bring more food. Let me cook again for Lord Nṛsiṁhadeva."
Then Śivānanda Sena again brought the ingredients with which to cook, and Pradyumna Brahmacārī again cooked and offered the food to Nṛsiṁhadeva.
One day, in the presence of all the devotees, the Lord raised these topics concerning Nṛsiṁhānanda Brahmacārī and praised his transcendental qualities.
Vāsudeva Datta, Murāri Gupta, Gaṅgādāsa, Śrīmān Sena, Śrīmān Paṇḍita, Akiñcana Kṛṣṇadāsa, Murāri, Garuḍa Paṇḍita, Buddhimanta Khān, Sañjaya Puruṣottama, Bhagavān Paṇḍita, Śuklāmbara Brahmacārī, Nṛsiṁhānanda Brahmacārī and many others joined together to go to Jagannātha Purī. It would be impossible to mention the names of them all.
