What is the nature of Sai Baba as described in the opening verses of Chapter 30 of the Sai Satcharitra?

Chapter 30 begins by portraying Sai Baba as the 'Karuṇālaya,' or abode of mercy, whose very darshan is powerful enough to dispel a devotee's fear of worldly existence. The text explains a profound theological concept: initially, Sai resides as the formless (Nirguni), but through the power of a devotee's love and devotion, He is drawn into a form with attributes (Saguni). Described as the crest-jewel among saints, the chapter emphasizes that His fundamental, unavoidable task is the spiritual uplifting of His devotees, a responsibility He cannot escape.
