How does Chapter 20 describe Sai Baba's fundamental nature and his appearance to devotees?

Chapter 20 of the Sai Satcharitra explains that Sai Baba is 'originally formless.' However, for the sake of his devotees, he took on a physical form, playing the role of 'Maya' like an actor on a stage. The chapter encourages devotees to meditate on this form. It also describes his physical presence in Shirdi, particularly after the noon Aarti, where he would stand at the edge of the Masjid and lovingly distribute Udi. His gaze is described as 'most merciful,' and his heart is filled with 'boundless love' for his followers, showing how his formless nature manifested as a compassionate, tangible presence for those who sought him.
