How does Chapter 30 portray Sai Baba's fundamental nature and his relationship with his devotees?

Chapter 30 of the Sri Sai Satcharitra portrays Sai Baba as the very "abode of mercy" (Karuṇālaya), whose darshan alone can dispel a devotee's fear of worldly existence. A key teaching is that while Sai initially resides in a formless (Nirguni) state, it is through the qualities of a devotee's devotion that He is drawn into a form with attributes (Saguni). This chapter emphasizes that His primary task is the upliftment of His devotees, a responsibility He cannot escape. Holding onto His feet is said to lead to the dissolution of all sins, making the spiritual path fearless and free of obstacles.
