What is the core message of Chapter 30 regarding Sai Baba's nature and his relationship with devotees?

Chapter 30 of the Sai Satcharitra portrays Sai Baba as the compassionate 'abode of mercy' (Karuṇālaya) whose very darshan dispels the fear of worldly existence. A key teaching is how He transitions from a formless (Nirguni) state to a form with attributes (Saguni) solely through the qualities of his devotees' devotion. This chapter emphasizes that uplifting devotees is an unavoidable task for saints like Sai, who is the teacher of all saints. It assures followers that holding onto His feet dissolves all sins and makes one's path fearless, as Sai knows and fulfills the innermost desires of His devotees.
