What is the ultimate spiritual reward promised to devotees who faithfully read and share the Shri Sai Satcharita?

According to the preface, a profound spiritual destiny awaits those who engage with the Shri Sai Satcharita. Chapter 0 explains that if devotees consume this "sweet, spiritual treat" with faith and encourage others to do the same, they perform a 'Jnana-yagna' or sacrifice of knowledge. The ultimate reward, as supported by verses from the Shri Dnyaneshwari, is that after the death of the body, these faithful individuals will "undoubtedly become one with the six-fold glorious Shri Sai-Paramatma." This union is achieved by offering the ignorance of the ego as an oblation to the Supreme Soul.
