What was author Annasaheb's great desire for the Shri Sai Satcharita, and what are the promised benefits for devotees who honor this wish?

According to Chapter 0, it was the great desire of the author, Annasaheb, that the Shri Sai Satcharita be studied and recited daily through Parayans and Saptahs, much like the revered Guru Charitra. Although he did not live to see this wish fulfilled, the preface explains the profound benefits for devotees who honor his intention. By consuming this 'sweet, spiritual treat (Prasad-meva)' with faith and encouraging others, devotees are said to satisfy Shri Sai-Paramatma through the 'sacrifice of knowledge (Jnana-yagna).' The ultimate promised benefit is that after the death of the body, these seekers will 'undoubtedly become one with the six-fold glorious Shri Sai-Paramatma.'
