Drawing from the Dnyaneshwari quotes in the preface, what is the transformative process a faithful reader of the Shri Sai Satcharita undergoes?

The preface, citing the Shri Dnyaneshwari in Chapter 0, outlines a profound transformative process for the faithful reader. The dialogue within the book gives birth to the 'dharma of salvation.' A person who reads it faithfully without differentiation engages in a sacrifice of knowledge. By 'offering the ignorance of the ego as an oblation' through the fire of knowledge, the reader satisfies the Supreme Soul. This spiritual practice culminates in the ultimate union, as it is stated that one who brings this teaching to other devotees 'after his body, becomes one with Me.'
