How does Chapter 20 explain the dual nature of Sai Baba as both formless and with form?

In Chapter 20 of the Sai Satcharitra, Sai Baba's nature is described as being originally formless. However, for the benefit and sake of his devotees, he took on a physical form. The text beautifully explains this by stating he accepted the role of the actress 'Maya' and truly played his part like an actor. This illustrates that his physical manifestation was a compassionate act to make himself accessible to his followers. The chapter also refers to Sai as a 'Siddhashram,' an abode of the perfected, whose mere sight relieves the fatigue of worldly life and drives away the delusion of existence for those close to him.
