What philosophical insights does Chapter 20 offer about Sai Baba's true nature and his connection to his devotees?

Chapter 20 presents Sai Baba as a being who is "originally formless" but took on a physical form for the benefit of his devotees, likening his role to an actor playing a part. The chapter describes Shirdi as a "Siddhashram," or an abode of the perfected, where the mere sight of Sai is enough to relieve the fatigue of worldly life and drive away delusion. He is hailed as a refuge who can end the cycle of rebirths and provide eternal rest. This divine nature is contrasted with his very human and loving interactions, such as the tender distribution of Udi, which underscores his deep, personal connection to his followers as described in the text.
