How does Chapter 20 describe Sai Baba's true nature and the form he took for his devotees?

Chapter 20 of the Sai Satcharitra explains that Sai Baba is "originally formless" but graciously took on a physical form for the benefit of his devotees. The text uses the analogy of an actor, stating that Baba accepted the role of "Maya" and played his part perfectly. This chapter also describes him as a Siddhashram, an abode of the perfected, whose mere sight can relieve the fatigue of worldly life and drive away the delusion of existence for those who are close to him. It encourages devotees to meditate on his form, bringing him into their minds to experience his presence.
