Sri Chaitanya Mahaprabhu appeared on this earth in 1486 AD., is considered to be joint incarnation of both Srimati Radharani and Sri Krishna in one body. He introduced Harinaam Sankirtan and preached to the people to perform such Kirtan in whatever time and whichever place they are. He said that power of the Holy name of God, one may develop deep love for God which may even be to the extent of love that the Gopies have for Shri Krishna. In His multi-various activities, both religious and social, Shri Chaitanya was assisted by His closest companion Shri Nityananda Prabhu.
Shri Chaitanya Mahaprabhu realized true feelings expressed in Vedas, Upanishads, ShrimadBhagavatam, epics and other religious books. His realization made him a great scholar as well as great social reformer. He declared that within the physical bodies of all living beings, dwells the soul which is an infinitesimal part of God Himself and therefore all the living beings are basically equal. He preached that one should leave the path of pride and be polite to such extent to think himself even lower than a blade of grass. One should be tolerant like a tree.
About five hundred years ago, Lord Sri Krishna Chaitanya Mahaprabhu personally came to the very place presently known as Sri PathBari Ashram Kolkata, and was thrilled to listen to the discourse on Srimad Bhagavatam presented by Sri Raghunatha Upadhaya. Lord Sri Chaitanya Mahaprabhu took great pleasure in conferring the title Sri Bhagabatacharya on Sri Raghunath Upadhaya then and there. Today Sri PathBari Ashram is not only a temple but also an important institution for the students of Sanskrit and Vaishnava Philosophy.
Shri Chaitanya Mahaprabhu disappeared at the young age of forty-eight only. Shri Radharaman Charan Das Babaji with his divine power revived the Sankirtan chanting about three hundred fifty years after the disappearance of Shri Chaitanya Mahaprabhu. He sincerely followed the teachings of Shri Chaitanya and revived many of the activities or Lila of Shri Chaitanya Mahaprabhu, which people had already forgotten by then. He was a living embodiment of Shri Chaitanya Mahaprabhu's universal religion of love. He carried Chaitanya Mahaprabhu's message of love from place to place, door to door and person to person, singing and dancing, laughing and weeping in rapturous ecstasies like Mahaprabhu Himself. He told us how all our sufferings could be easily removed and we could attain the highest goal of life-the attainment of the lotus feet of the lord and his loving service only through Sankirtan or the congregational chanting of His name (Bhaja) Nitai Gaur Radhe Shyam, (Japa) Hare Krishna Hare Ram. Since we, the jives of kali, would not easily believe him, he mercifully took it upon Himself to demonstrate to us the inconceivable power of the Divine Name by curing diseases, melting stones, making the tree dance and animals behave like Vaishnavas devotee, and even by bringing the dead back to life through the chanting of the Name "Bhaja Nitai Gaur Radhe Shyam, Japa Hare Krishna Hare Ram". He taught both by example and by precept the religion of pure Bhakti. He stands out prominently before us as the very embodiment of truth.
