The second "Avatar" (incarnation) of Lord Datta in this age of Kali was in the form of Sri Nrusimha Saraswati. To the pious couple, Madhava Sharma and his wife Amba, who lived in a village named Karanja or Laad-karanja in the State of Maharashtra, was born this divine child who amazed every one from the time of his birth, not by crying, but by uttering clearly the "Pranava-Nadam" (the sound of OM). The child named "Narahari", grew upto be a handsome boy of five, but he could not speak. This was a cause of worry to the Parents.One day the young boy conveyed to his mother that he would speak if his "upanayanam" was performed. No sooner than the child was invested with the sacred thread, the divinity in the child swelled out and keeping his promise, he started reciting all the Vedas and immediately sought "Bhiksha" from his mother. He then did "pradakshina" (pacing in a circle thrice around a person(s)/deity etc.) of his Parents and sought their permission to enter the "Sanyasa Ashrama", (i.e. the fourth Stage of religious life). When they remonstrated to him that he was their only son, he blessed them with his divine form and presented them the wisdom that he was not an ordinary mortal. After a year, with the birth of twins to his parents, they permitted him to renounce the world and he left his home dressed as renunciate. On his way to Badrinath, Narahari visited Varanasi (Kashi) and in accordance with holy tradition, resorted to His Holiness Swami Krishna Saraswati as his "Guru" and from him took the vow of "Sanyasa" and he came to be known as Sri Nrusimha Saraswati. He thereafter visited various Holy places and during the course of his wanderings blessed many devotees, had caused many divine miracles to happen and resurrected many forgotten Holy places like Karaveerapuram, Bhillavati, Ganagapuram etc. The very Trinity in human form that he was, Sri Nrusimha Saraswati, performed many leelas beyond the comprehension of the mortal mind. Like in his previous incarnation, Sri Nrusimha Saraswati, ended his incarnation by sitting on a float with the leaves of banana and flowers on the waters of river Krishna in Patala Ganga, near Srisailam and drifted along the flowing river to merge in the Pure conciousness.
