According to the teachings in Chapter 50, what is the fundamental nature of Sai Baba, and how does he express his compassion?

Chapter 50 presents Sai Baba as the embodiment of pure consciousness, describing him as the Unmanifest who has taken a manifest form for the sake of his devotees. His nature is desireless, yet he is deeply compassionate towards the faithful. This compassion is expressed through his willingness to share his own life story, which the text refers to as a 'temple' for his loving listeners. Furthermore, Chapter 50 explains that when Sai places his hand upon a devotee's head, their ego is destroyed, and they begin to realize their true nature through the chant of 'So-ham' (I am He), filling their perception with joy.
