Sree Nityananda Prabhu, the Associated Facsimile of Sree Chaitanya, made His appearance in the village of Ekchaka in the country of Rahr, not far from Mollarpur station of the E.I. Railway, within the modern district o f Birbhum. Hadai Pandit or Hadai Ojha, the father of Nityananda, was a good Brahmana from Mithila, resembling Vasudeva in the immaculate purity of his nature. The name of the wife of Hadai Pandit was Padmavati. Nityananda made His appearance in this world on the tithi which is ever hallowed by His birth, that corresponds to the thirteenth day of the bright fortnight of the month of Magh. As a child, Nityananda startled all the neighbours by being constantly occupied in the company of His associates in rehearsing the events of the Avataras of Vishnu. The details of these childish pastime have been reverentially preserved. Their nature may be briefly indicated.

He made His playmates form themselves into the assembly of gods. One of the boys, representing the Earth, having complained to it of her unbearable sufferings under the crushing weight of iniquities, those children who acted as members of the assembly of gods repaired to the bank of the adjoining river and there prayed to the Lord Who rests in the Ocean of Milk. One of the boys, hid behind the tree, gives this reply of Godhead to their prayer, 'I will soon be born in the Home of Vasudeva at Mathura'. Sometimes personating the Divine Avatara of the Dwarf, Nityananda affected to deliver Bali. On another occasion He would fall into a swoon acting the part of Lakshmana in the Leela of Godhead's Avatara as Sree Ramachandra hit by the powerful dart of Indrajit. Then one of the boys, acting the part of Hanuman, hastened to procure the required curative herb from the Gandhamadana Mount and by that means effected His recovery. Such pastimes of the little Boy amazed all beholders who could not account for this extraordinary conduct of the little Child. Twelve years were passed in these pleasant activities under the roof of His parents.

Everyone is engaged in action. The law of karma means that there are reactions to every action and that a person must endure the reactions to his actions.

Nityananda set out on His long travel to all places of pilgrimage at the age of twelve. The incident that immediately led to this long pilgrimage is thus stated. A certain sannyasin became a chance-guest at the house of Hadai Pandit. He begged of Hadai Pandit to give Nityananda to him; and, in order not to transgress against the rule laid down by the Shastras, Hadai Pandit found himself obliged, against his own wish, to hand to the sannyasin the Darling of his heart Who was much more to him than even his own life. The grief of the parents, in being thus parted for good from their Child of twelve, knew no bounds. The nature of the renunciation of the world for the sake of Godhead must on no account be confounded with renunciation for any other purpose, which latter is an unpardonable and clear dereliction of one's duty. The renunciation exhibited by Godhead and His devotees redounds to the good of the whole world, and, most of all, of those very persons who appear, to the superficial observer, to be the greatest sufferers by their abandonment.
