How does the story of Walya turning into Valmiki illustrate the transformative power of chanting Rama's name?

The transformation of Walya into Valmiki serves as a powerful testament to the redemptive power of God's name. As recounted in Chapter 19, Walya was a highway robber, a fallen man. He was redeemed through the simple, albeit reversed, repetition of Rama's name. By chanting 'Mara Mara,' the name 'Rama' eventually appeared on his tongue. This act of remembrance and repetition purified him so completely that he became the great sage Valmiki. The miracle was so profound that he gained a miraculous mastery over speech and was able to compose the epic story of Rama's life even before Rama was born. This illustrates that chanting the name can purify even the most fallen individuals and lead to miraculous spiritual attainment.
