I'm looking for details about Saint Augustine, but he's not mentioned. What does the book advise for devotion when a specific figure isn't named?

The text provides guidance through a story of personal experience in Chapter 19, which illustrates that the devotee's internal resolve is what attracts grace. The author decided to continuously chant the name of Rama, and upon waking and setting out, he heard a song with the refrain, 'I have found the collyrium of Guru’s grace... I do not believe in anything without Rama.' This experience is presented to show how Maharaja gives encouragement when one begins to regulate good thoughts. The advice is to nurture these good thoughts, as this will lead to great satisfaction and peace, confirming that the Guru responds to the devotee's sincere intention, regardless of whether a specific name is cataloged in a book.
