What is the ultimate spiritual benefit promised to those who faithfully read the Shri Sai Satcharita?

The preface in Chapter 0 outlines a profound spiritual benefit for devoted readers. The book is presented as a 'spiritual treat' for seekers. It is stated that if devotees consume this treat with faith and encourage others to do so, they will satisfy Shri Sai-Paramatma with a 'sacrifice of knowledge' (Jnana-yagna). The ultimate promised outcome, as described in the text, is that after the death of the body, these faithful seekers will undoubtedly become one with the six-fold glorious Shri Sai-Paramatma, achieving a state of union.
