How does Chapter 30 of the Sai Satcharitra explain Sai Baba's nature as both formless and with form?

Chapter 30 presents a profound philosophical concept about Sai Baba's divine nature. It states that in the beginning, He resides as the formless (Nirguni). However, it is through the compelling qualities of his devotees' devotion that He is drawn from this formless state into a tangible form with attributes (Saguni). This teaching, found in the chapter's opening verses, illustrates that the divine manifestation in a physical form is a compassionate response to the faith and love of the followers, positioning Sai Nath as the 'crest-jewel among saints' who takes form for their sake.
