Based on Chapter 40, what is the significance of singing the praises of a devotee, and what evidence is cited to support this idea?

Chapter 40 puts forth a profound spiritual concept: God, or Hari, is immensely pleased when someone sings the praises of His devotees, even more so than when praised Himself. This idea is central to the author's motivation for writing the Satcharitra, which is a collection of stories about Sai and His devotees. Recognizing that listeners might find this statement doubtful, the author, as guided by Sai's inspiration, provides a scriptural reference. Chapter 40 states that one should 'look at the Bhavishyottara Purana, where Tripurari (Shiva) states this,' thereby lending ancient authority to the claim that glorifying devotees is a highly cherished spiritual practice.
