Sri Nityananda Trayodashi is the auspicious appearance day of Nityananda Prabhu. The Supreme Lord Sri Krishna appeared in Navadvipa as Sri Chaitanya Mahaprabhu to establish the Sankirtana Movement (the yuga dharma for this age of quarrel and hypocrisy). To help the Supreme Lord in His mission, Lord Balarama appeared as Nityananda Prabhu. He assisted Sri Chaitanya Mahaprabhu by spreading the holy name of the Lord throughout Bengal.
The Appearance of Lord Nityananda
Nityananda Prabhu appeared in the village of Ekachakra, in the district of Birbhum (West Bengal) as the son of Padmavati and Hadai Pandita in the year 1474 AD. He was born on the thirteenth day of the bright fortnight in the month of Magha (Magha Shukla Trayodashi). Even today pilgrims visit the place of birth of Lord Nityananda in Ekachakra. This temple is called Garbhavasa. The parents of Lord Nityananda hailed from the family of pious brahmins originally from Mithila.
Nityananda Prabhu is an eternal associate of Sri Chaitanya Mahaprabhu. Vaishnava acharyas emphatically state that people who try to understand Chaitanya Mahaprabhu without getting the mercy of Nityananda Prabhu will never succeed and one must pray very sincerely to Lord Nityananda Prabhu as the adi-guru (original spiritual master) to be delivered to the Lotus feet of Sri Chaitanya Mahaprabhu.
