According to the introductory verses of Chapter 20, what is the nature of Sai Baba and how does he interact with his devotees?

The beginning of Chapter 20 describes Sai Baba as a 'Siddhashram,' an abode of the perfected, whose mere sight relieves the fatigue of worldly life. It states that Sai, who is originally formless, took on a physical form for the sake of his devotees, playing the role of 'Maya' like an actor. This chapter portrays him as a being of immense grace who ends the cycle of rebirths and provides the shelter of eternal rest. In his interactions, such as during the Udi distribution after the noon Aarti, his 'boundless love' is evident as he mercifully tends to his devotees' needs, both spiritual and material, by giving them sacred ash and lovingly urging them to go eat.
