How does Chapter 20 explain the nature of Sai Baba in relation to his form and his effect on people?

According to Chapter 20, Sai Baba is described as being "originally formless" but having taken on a physical form purely for the sake of his devotees. The text uses the metaphor of an actor, stating he accepted the role of "Maya" to play his part. The power of his presence is also highlighted, as it is said that the mere sight of him could relieve the fatigue of worldly life. For those who were close to him, his constant presence was powerful enough to drive away the "delusion of existence," establishing him as a Siddhashram, or an abode of the perfected.
