How does Chapter 20 describe Sai Baba's fundamental nature and the way He interacted with His devotees in Shirdi?

Chapter 20 presents a dual perspective on Sai Baba's nature. It begins by stating that Sai is "originally formless" but took on a physical form for the sake of his devotees, playing the role of "Maya" like an actor. This highlights his divine, transcendental essence. Yet, in this physical form, his interactions were filled with immense love. The chapter vividly describes him after the noon Aarti, personally distributing Udi to each devotee, applying it to their foreheads, and then affectionately urging them to go and eat. This act demonstrates how his formless nature manifested as tangible, boundless love for those who came to him.
