How does Chapter 40 justify the practice of praising a Guru's devotees, and who is credited as the ultimate source of the Satcharitra's inspiration?

Chapter 40 provides a specific justification for singing the praises of devotees. It states that Hari (God) Himself is more pleased when someone sings the praises of His devotees than when they sing praises of God. To give this statement a solid foundation and address potential doubt from listeners, the text, as noted in Chapter 40, points to the Bhavishyottara Purana, where Tripurari (Shiva) affirms this very principle. Regarding the book's inspiration, the chapter is unequivocal: the entire work is Sai's inspiration. The author insists that Sai is the 'original stimulator of consciousness' who 'performs His own story,' and that the author, Hemad, is merely a puppet acting under Sai's direction.
