How does the preface to Shri Sai Satcharita use teachings from the Dnyaneshwari to explain the book's value?

The preface extensively references the Dnyaneshwari to elevate the Shri Sai Satcharita's literary and spiritual status. As seen in Chapter 0, it quotes Dnyaneshwari Chapter 18 to define the book's aesthetic, where the beauty of poetry is perfected by the "touch of the Supreme Truth." Furthermore, it uses other verses from Dnyaneshwari Chapter 18 to explain the soteriological benefits of reading the Satcharita, equating the act of reading with a 'sacrifice of knowledge' where the reader satisfies the Supreme Soul and is promised to become one with the divine after death, thus framing the Satcharita within a well-established philosophical tradition.
