Chapter 40 provides a scriptural justification for singing the praises of a Guru's devotees. Can you explain this justification and its context?

Indeed, Chapter 40 addresses the potential doubt listeners might have about the value of praising devotees. The text states that Hari (God) is even more pleased when someone sings the praises of His devotees than when they sing praises of God Himself. To provide a solid foundation for this claim, the author directs the reader to the Bhavishyottara Purana, where Lord Shiva (Tripurari) makes this very statement. The author then clarifies that this insight itself is an inspiration from Sai, approved by Him for the spiritual benefit of His followers, thereby validating the stories within the Satcharitra.
