How does Chapter 30 portray Sai Baba's dual nature as both formless and with form?

Chapter 30 begins by describing Sai Baba's fundamental nature as formless (Nirguni). However, it explains that it is through the qualities of a devotee's devotion that this formless essence is drawn into a form with attributes (Saguni). The chapter beautifully illustrates this transition, calling Sai Nath the "crest-jewel among saints" who takes on a form out of compassion for His followers. This highlights the teaching that the divine, while inherently beyond attributes, manifests in a perceivable form for the sake of the devotee, as mentioned in the opening verses of the chapter (Chapter 30).
