How does Chapter 20 describe Sai Baba's essential nature and his physical form?

According to Chapter 20, Sai Baba is described as being originally formless. However, for the benefit and sake of his devotees, he took on a physical form, accepting the role of "Maya" and playing his part like an actor. This chapter also refers to Sai as a Siddhashram, or an abode of the perfected, whose mere sight is enough to relieve the fatigue of worldly life. It states that his constant presence drives away the delusion of existence for those who are close to him, highlighting both his transcendental nature and his compassionate, embodied presence.
