Sriman Mahaprabhu & Nityananda Prabhu & Sri Advaita Prabhu

Deities – Sri Advaita, Sriman Mahaprabhu, Sriman Nityananda Prabhu, Nandanacharya prabhu, and Sudevi Mata

Nandana Ācārya, the seventeenth branch of the Caitanya tree, is celebrated within the world because the two Prabhus (Lord Caitanya and Nityānanda) sometimes hid in his house. Nandana Ācārya was another companion of Lord Caitanya Mahāprabhu during His kīrtana pastimes in Navadvīpa. Śrīla Nityānanda Prabhu, as Avadhūta, traveled on many pilgrimages, and when He first came to Śrī Navadvīpa-dhāma He remained hidden in the house of Nandana Ācārya. It is there that He first met all the devotees of Lord Caitanya Mahāprabhu. When Caitanya Mahāprabhu exhibited His mahā-prakāśa, He asked Rāmāi Paṇḍita to call Advaita Prabhu, who was hiding in the home of Nandana Ācārya, for Śrī Caitanya Mahāprabhu could understand that He was hiding. Similarly, Lord Caitanya also sometimes hid in the home of Nandana Ācārya. In this connection one may refer to Śrī Caitanya-bhāgavata, Madhya-khaṇḍa, Chapters Six and Seventeen.
(CC Adi 10.39, Translation and Purport)

On realizing this, He immediately went to Navadvīpa, where He stayed at the house of Nandana Ācārya. Nandana Ācārya was a mahā-bhāgavata. He saw that the bodily effulgence of Nityānanda was equal to the sun.
(Śrī Caitanya-bhāgavata, Madhya-khaṇḍa 3.124 – 3.125)

Prabhupāda: Parama koruṇa, pahū dui jana, nitāi gauracandra. This is a song by Locana dāsa Ṭhākura, a great devotee and ācārya of the Gauḍīya-sampradāya. He is declaring that pahū dui jana. Pahū means lords. Dui jana means two. Who are the two Lords? Nitāi Gauracandra. One is Lord Nitāi, Nityānanda; another is Lord Śrī Caitanya Mahāprabhu.
So he says that, “These two Lords are very merciful.” Parama koruṇa, pahū dui jana. Parama koruṇa means very merciful. Nitai Gauracandra. Saba avatāra, sāra śiromaṇi. Avatāra means incarnation, and saba means all. “They are the essence of all incarnations.” Saba avatāra, sāra śiromaṇi, kevala ānanda-kanda: “And the specific significance of these incarnations is that to prosecute Their ways of self-realization is simply joyful,” ānanda-kanda.
They introduced chanting and dancing. No other incarnation . . . there are many incarnation, just like Lord Rāma. Even Kṛṣṇa, He taught Bhagavad-gītā. That requires knowledge, understanding. But here Lord Caitanya, Nityānanda, introduced some process which is simply joyful: simply chant and dance. Kevala ānanda-kanda. Saba avatāra, sāra śiromaṇi, kevala ānanda-kanda.
Therefore he requests everyone, bhajo bhajo bhāi, caitanya nitāi: “My dear brothers, I request you. Just you worship Lord Caitanya and Nityānanda” sudṛḍha biśwāsa kori’, “with firm conviction and faith” Don’t think that this chanting and dancing will not lead you to the desired goal. It will, because there is assurance of Lord Caitanya Mahāprabhu that you will get all perfection by this process.
