Valmiki was not just saint poet in his earlier life and was known in the name of Ramakara,
Seven seers , who once fell a victim to his depredation, awakened him to the reprehensible nature of his conduct and instructed him in the holy name Rama,
Completely immersed in sin he was, however, unable to utter the word, the seers therefore, asked him to repeat the name in the reverse order,
In this way he was eventually able to utter the name correctly and in course of time become so fond of repeating it that ultimately turned out to be a pious sage and related the story of Sri Rama in the fine verse even before the advent,
May Lord Bless all,
Thanks please
