How does Chapter 30 explain Sai Baba's manifestation from the formless to a form with attributes?

According to the teachings presented in Chapter 30, Sai Baba initially resides in a formless, or Nirguni, state. The text explains that it is the power of the devotees' devotion and its inherent qualities that draw the formless divine into a tangible form with attributes, known as Saguni. This illustrates a profound spiritual concept where the devotee's faith and love are the catalysts that manifest the unmanifested. The chapter refers to Sai Nath as the 'crest-jewel among saints' in this context, highlighting the significance of this divine transformation driven by the devotee's heart.
