How does Chapter 20 describe Sai Baba's nature and his reason for taking a physical form?

Chapter 20 explains that Sai Baba is originally formless but took on a physical form for the sake of his devotees. It beautifully illustrates this by stating he accepted the role of the actress 'Maya' and truly played his part like an actor. This chapter portrays him as a 'Siddhashram' or an abode of the perfected, whose mere sight relieves the fatigue of worldly life. For those close to him, his constant presence is said to drive away the delusion of existence, showcasing his compassionate and divine nature.
