How does Chapter 20 describe Sai Baba's spiritual nature and his role for devotees?

Chapter 20 presents Sai Baba as a 'Siddhashram,' or an abode of the perfected, whose mere sight relieves the fatigue of worldly life and drives away delusion for those close to him. It philosophically states that Sai is originally formless but took on a physical form for the sake of his devotees, comparing him to an actor playing the part of 'Maya.' This portrayal emphasizes his compassionate nature and his function as a spiritual refuge who can end the cycle of rebirth for those who surrender to him.
