How does Chapter 30 describe the transition of Sai Baba's nature from formless to having a form?

Chapter 30 of the Sai Satcharita poetically explains that Sai Baba initially resides as the formless, or Nirguni. However, it is through the compelling qualities of His devotees' devotion that He is drawn from this formless state into a perceptible form with attributes, known as Saguni. The text venerates Him as the "crest-jewel among saints" and an "abode of mercy" (Karuṇālaya), emphasizing that the task of uplifting devotees is an inescapable duty for a saint of His stature. His very darshan is said to dispel the devotees' fear of worldly existence.
