According to the text, how is Sai Baba's divine form and purpose described at the beginning of Chapter 38?

The initial verses of Chapter 38 offer powerful salutations and descriptions of Sai Baba's divine essence and mission. He is hailed as the "Granter of joy to the entire world" and the "Protector of those who bow" to Him. The chapter beautifully portrays Him as the "Destroyer of duality" and the "Enchanter of the minds of devotees." It describes His form as a "beautiful idol" shaped from the "pure essence of Self-form," essentially the very mold of Brahman. According to this chapter, Sai is identified as Atmaram, the abode of perfect bliss, who, despite being desireless himself, helps his devotees become desireless.
