The preface to the Satcharita quotes the Dnyaneshwari. What is the context of these quotes and what do they convey about the text's purpose?

The preface in Chapter 0 uses quotes from the Dnyaneshwari to elevate the Shri Sai Satcharita's spiritual and literary status. One quote from Dnyaneshwari Chapter 18 defines true poetic beauty as the "touch of the Supreme Truth," which the Satcharita is said to possess. Other quotes from the same chapter emphasize the book's role as a form of knowledge sacrifice, or "Jnana-yagna." They convey that by faithfully reading and sharing this "secret mantra," the devotee offers the ignorance of the ego as an oblation, satisfying the Supreme Soul and ultimately becoming one with Him after the body's passing.
