How does Chapter 30 describe Sai Baba's transformation from a formless state to one with a form?

Chapter 30 of the Sri Sai Satcharita explains that Sai Baba initially resides in a formless, or Nirguni, state. However, it is through the qualities and devotion of his followers that he is drawn into a form with attributes, becoming Saguni. This concept, presented in the chapter's opening verses, beautifully illustrates how the formless divine manifests in a tangible form in direct response to the love and faith of devotees. This establishes Sai Nath's position as the 'crest-jewel among saints' who can bridge the formless and the formed for the sake of his followers.
