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

Chapter 30 of the Sri Sai Satcharitra explains this concept by stating that Sai Baba initially resides as the formless (Nirguni). However, it is through the qualities of his devotees' intense devotion that the formless is drawn into a tangible form with attributes (Saguni). The text poetically describes this transition as a response to the love of his followers, positioning Sai Nath as the 'crest-jewel among saints' who manifests for their sake. This illustrates a profound theological point about the divine responding to and taking form for the benefit of the devotee, as highlighted in the opening verses of this chapter.
