According to Chapter 40, why is singing the praises of devotees considered important, and what scriptural evidence is provided?

Chapter 40 highlights a significant spiritual principle: God (referred to as Hari) is immensely pleased when one sings the praises of His devotees, even more so than when one praises God Himself. The author acknowledges that some listeners might find this statement doubtful. To provide a solid foundation for this claim, the text directs the reader to the Bhavishyottara Purana. As mentioned in the chapter, this ancient text contains a statement by Tripurari (an epithet for Lord Shiva) that confirms this very teaching. The author clarifies that this insight itself is an inspiration from Sai Baba for the spiritual welfare of all His followers.
