Chapter 20 states that Sai is 'originally formless.' How does the chapter explain his presence in a physical form and its effect on devotees?

The text of Chapter 20 explains that while Sai Baba is 'originally formless,' he took on a physical form specifically for the sake of his devotees. The chapter uses the metaphor of an actor, stating that Baba accepted the role of the actress 'Maya' and played his part perfectly. The purpose and benefit of this physical manifestation are also highlighted. The scripture mentions that the mere sight of Sai relieves the 'fatigue of worldly life,' and his constant presence has the power to drive away the 'delusion of existence' for those who are close to him.
