As the story goes, Ratnakar was a robber who had taken to robbing and would loot people passing from one village to another. During one such incident he came across Narada Muni and threatened him with dire consequences if he did not part with all he had. Narada got him chatting and asked him the reason of this profession, to which Ratnakara said that he was doing this for his family. Did he know that the means were wrong, to which Ratnakara said that he did, but he had no option as he had to take care of his family too.
Then Narada asked him, if his family would be party to his sin, to which Ratnakara felt, that they obviously would. On Narada’s insistence, Ratnakara went home to check with his family. To his horror and surprise, both his wife and children felt that it was his responsibility to take care of them, but they could not be hold responsible for the sin he was committing. Heart-broken, Ratnakara came back to the waiting Narada and broke down. It was then that Narada taught Ratnakara how to meditate and chant ‘Rama’.
Ratnakar got so engrossed in his meditation that he did not even realise that ant-hills had formed all over him. Later Narada, came and removed the ant-hills from his body and named him Valmiki, (Valmika meaning ‘from the ant-hill’) and gave him the title of Brahmarishi and in due course of time, motivated him to pen down the entire Ramayana, after narrating the story to him.
Here too, we find that Narada was instrumental in seeing the potential of Ratnakara and through the correct means transforms him into Brahmarishi Valmiki. This is thanks to his being aware of the fact that Ratnakar was the long lost son of Rishi Prachetasa, who was lost at childhood and brought up by a hunter, and in due course took to looting. This internal information was put to good use and channelized into making him a rishi and a great author. Narada’s being aware of critical information, making good use of it and influencing in the most positive manner enabled Valmiki to write the epic, Ramayana.
