How does Chapter 30 describe the fundamental nature of Sai Baba?

Chapter 30 of the Sri Sai Satcharita portrays Sai Baba as a compassionate abode of mercy (Karuṇālaya) whose very darshan can dispel a devotee's fear of worldly existence. The text explains a profound concept: initially, Sai resides in a formless state (Nirguni), but through the power of a devotee's love and devotion, He is drawn into a form with attributes (Saguni). This chapter identifies Him as the "crest-jewel among saints," highlighting His supreme spiritual status and His role as a teacher for other saints.
