How does the text explain the role of Guru's grace in the creation of the Shri Sai Satcharita?

The preface, discussed in Chapter 0, strongly emphasizes that Guru's grace is paramount in creating a spiritual work of lasting value. It states that no amount of scholarship or intelligence can substitute for it, and that the writing of the Shri Sai Satcharita itself is the very fruit of Sai Baba's grace falling upon Annasaheb. This grace imbues the work with qualities of inspiration and divine gift, which are essential for it to leave an impression on seekers and instill faith, a feat that a purely scholarly book could not achieve.
