Can you explain the significance and power of chanting Rama's name as described in the provided text?

The text in Chapter 19 describes the name of Rama as having immense power and significance. It is presented as a path to non-dual worship, where one can become one with Brahman. The benefits are said to be manifold, with the repetition of Rama's name having the power to stop the cycle of birth and death. An incredible example given is that of Walya, a robber who was redeemed by chanting the name in reverse ('Mara Mara'), which transformed him into the great sage Valmiki. This act allowed him to write the story of Rama's life even before Rama was born. The name is called a protector of the poor, capable of destroying millions of obstacles.
